SOURCE: Bike began running rough so I changed the oil,

"Oh, and now I can\'t even read the oil level on my dipstick due to the fact it is significantly LOW" This is not a good sign. Now, my expertise is NOT on the Twin Cam bikes but I do try to help when I can. In your case, if your engine were an earleir Evolution or Shovelhead engine, I'd say that you had sheared a scavenge gear drive key in the oil pump. Now, I do not know a thing about the oil pump in a Twin Cam as I've never worked on one. It sounds like your oil pump is not scavenging (sucking) the oil out of the engine and pumping it back to the oil tank. Once the pump pumps the oil into the engine, it stays there. Thats why you're seen the "massive amounts of oil spitting out of the little hoses behind the air cleaner". Take your bike to a dealer or qualified shop as soon as possible and I'd refrain from running it. An engine full of oil would also expain why the engine does not want to run as well.

Good Luck

My 2000 Road King bucks and hesitates when at low speed, now recently will stall out, what can I do?

You don't say if any work has been recently done to this engine, or if it has had regular maintenance such as tune-up or carb/fuel injector cleaning. My first thought is an extremely lean condition. Does it back-fire through the air cleaner?
Causes of lean condition could be dirty fuel filter, mal-adjusted carburetor idle circuit, dirty low-speed jets or fuel injectors, or even the ignition timing has slipped. If the filter hasn't been changed recently, do that first. Then, a simple solution for clogged fuel meters that oftentimes works is to add fuel-injector cleaner to your gas tank. An entire bottle to one tank (normally intended for a 17-gallon auto fuel tank) would be about right. Expect to do this for several tanks, then a couple times/year to keep the cab/injectors clean. If that doesn't work, time to get the tools out. Start with a Harley shop manual for your model. (If the cleaner makes things worse, your fuel tank is also filthy, and it's time to clean that as well as the carb/fuel injectors.)

My 1996 Mitsubishi Montero will start but not idle at all once driven. My father-in-law suggests adding some Sea-foam to the vacuum hose and the gas tank to help. My question is; where do I find the...

Back in the good old days, engines had various vac hoses that controlled other devices including the PCV valve. The idea was to use one of the vac hoses to pull SeaFoam directly into the intake and help clean deposits off the intake valves.
Today's engines have very few such hoses.
And in your case, the problem is probably dirty injectors or the throttle body itself.
So I would put the seafoam in the gas tank, but also check the throttle body to see if it is gummed up. You can use spray carb cleaner if it needs to be cleaned.

These are generic suggestions for small engines that will not start or run under the conditions you described in your question.

Engines that do not run often can often suffer from the use of stale fuel. Be sure the fuel is fresh. Drain old fuel and if not a very large quantity, you could mix with fuel in another tank (such as your automobile) that is used regularly and quickly or dispose of properly. Many fuel retailers have different formulas for fuels sold in different seasons of year that work best in the seasons in which they're sold. it's not to say a summer fule won't burn in the winter - but that a winter fuel will burn better in winter. Add fuel stabilizer to help keep gasoline in tanks of seldom used engines from growing stale.

Many gasoline powered small engines incorporate a "fuel shut off valve" either at the bottom of the tank (near the fuel hose connection) or an inline type valve on the fuel line itself. Make sure the valve is on - many times this means the handle is inline with the hose instead of perpendicular to it.

Have a look at the carb linkage. The linkage consists of the metal rods & springs that provides positioning of the carb components that increase and reduce the speed of the engine as the load changes to help maintain a steady output. The moving parts of the carb should not be gummed up or dirty and should move easily & freely. Use of carb cleaner products are ideal for cleaning these areas. Spraying cleaner into the throat of the carb will make starting difficult and as per instructions should be done in short bursts only while the engine is running. Do not attempt adjusting the screws on the carb as these are factory set and under most circumstances need no further adjustment.

The next thing to check is the fuel and air filters. If the fuel is old or has become clogged, it will be necessary to replace it. These filters are located between the fuel tank and carb. Many are located inline on the fuel hose. You should shut the fuel shut off valve if it is between the tank and the filter to prevent fuel from draining from the tank when the filter is removed (or have a container ready to capture the entire contents of the tank). The air filter usually becomes clogged before the fuel filter will - depending if it is operated in a dirty / dusty environment or not. You may be able to wash a sponge filter or use compressed air to clean a paper filter by directing air / water streams opposite of the normal airflow direction. Older foam filters will likely break apart and require replacement and paper filters contaminated with oil (unless designed to be in oil) may not clean up enough to allow enough air into the carb and require replacement.

Hopefully, one of these suggestions will work for you. Otherwise, it may be time for a professional small engine tune up. Good luck!

How to change the fuel filter

Fuel Filter The filter should be inspected for external damage and/or leakage at least once a year. The fuel filter should be changed only as necessary. Toyota Motor Corporation recommends replacing the carbureted fuel filters at 15,000 miles and 30,000 miles on fuel injected models. NOTE: Fuel lines and connections, fuel tank vapor vent system hoses and fuel tank bands should be inspected every 60,000 miles or every 36 months. The fuel tank cap gasket should be replaced 60,000 miles or every 72 months.
REMOVAL & INSTALLATION Carbureted Engines The fuel filter on carbureted engines is a plastic cylinder with two ports for the fuel. It is usually located in the engine compartment near the charcoal canister.
  1. Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner. Grasp the clamps and slide them up the hose slightly above the filter ends 88271p10.jpg

  2. Grasp the hoses near the ends and twist them gently to pull them free from the filter pipe. Slide the hose off the end of the fuel filter end 88271p11.jpg

  3. Pull the filter from the clip and discard. Be carefull when removing the filter, some fuel may spill out if not held upright 88271p12.jpg
    To install:
  4. Install the new filter into the clip. The arrow must point towards the hose that runs to the carburetor.
  5. Push the hoses onto the filter pipes, then slide the clamps back into position.
  6. Start the engine and check for leaks.
Fuel Injected Engines 1993-97 MODELS
  1. Turn the ignition switch to the LOCK position. Disconnect the negative battery cable and wait at least 90 seconds before proceeding with working on the fuel system. This will depressureize the fuel system. The fuel filter can be hard to locate on these engines 88271pa1.jpg
    Fig. 4: Exploded view of the fuel filter mounting - 1993-97 models 88271g02.gif
    Fig. 5: Disconnect the negative battery cable prior to all fuel system repairs 88271g03.gif
    Failure to depressurise the fuel system could cause personal injury.
  2. Disconnect the Intake Air Temperature (IAT) sensor wiring.
  3. Loosen the air cleaner hose clamp bolt, the disconnect the four air cleaner cap clips. Fig. 6: Loosen the air cleaner hose clamp bolt 88271g04.gif

  4. Spearate the air cleaner hose from the throttle body, and remove the air cleaner cap together with the air cleaner hose.
  5. Disconnect the EVAP canister hose from the charcoal canister. Fig. 7: Remove both EVAP hoses from the charcoal canister 88271g05.gif

  6. Remove the charcoal canister from the bracket.
  7. Place a suitable container or shop towel under the fuel filter. Remove the union bolt and two gaskets, then slowly disconnect the fuel inlet hose from the fuel filter outlet. Fig. 8: Remove the union bolt and two gaskets from the fuel filter, then disconnect the inlet hose from the filter 88271g06.gif

  8. Using a special wrench 09631-22020 or equivalent, disconnect the inlet pipe from the fuel filter. Remove the two bolts and the filter from the vehicle. Fig. 9: Using a special tool, disconnect the inlet pipe from the fuel filter 88271g07.gif
    Fig. 10: Remove the two filter mounting bolts, then separate the filter from the vehicle 88271g08.gif
    To install:
  9. Install the fuel filter with the two bolts and tighten them to 43 inch lbs. (5 Nm).
  10. Using the special wrench 09631-22020 or equivalent, connect the inlet pipe to the fuel filter. Tighten to 22 ft. lbs. (30 Nm). Using a torque wrench, tighten with a fulcrum length of 11.81 inch (30cm). Install the fuel inlet hose to the filter outlet using new gaskets and union bolt. Tighten to 22 ft. lbs. 30 Nm). Fig. 11: Install the filter inlet hose to the filter outlet, then tighten to 22 ft. lbs. (29 Nm) 88271g09.gif

  11. Install the charcoal canister to the bracket. Connect the two EVAP hoses to the canister.
  12. Connect the air cleaner hose to the throttle body. Install the air cleaner cap together with the air cleaner hose.
  13. Attach the IAT sensor wiring.
  14. Connect the negative battery cable. Start the engine and check for leaks. Reset any various digital equipment such as radio memory and the clock if necessary.

Try cleaning the throttle body with throttle body cleaner. Remove intake hose at throttle end. Spray cleaner on butterfly and open throttle by hand, spray inside throttle body and let the build up run back out. Wipe clean with clean dry cloth, and repeat. It will be hard to start after putting back on, but it will start with 5-6 engine turns. It's the cleaner in the throttle. The injectors ca be cleaned with them in, they will run clean the fuel system. I usually buy Lucas injector cleaner and add 109 octane booster from wal-mart or your local parts store. Lucas is wonderful and the booster will clean your system. A lot cheaper than a shop cleaning it.

I can put a little gas in carb and it will crank and run about half minute then quit

If you did nothing to the carburetor adjustments, are using a fresh (1.5 months or less) fuel mix with the same fuel/oil ratio (I recommend 50:1 = 1 gal super not regular gas to 2.6 oz quality 2 cycle engine oil), are operating at the same elevation, and the air filter is clean, there is a reason your saw is acting up.
Most often it is a fuel delivery problem. Check the fuel filter on the free end of a hose in fuel tank (manufacturer recommends an annual replacement). Check all fuel delivery lines especially at fittings and bends for cracks and holes. If those are good then the likely cause is internal parts of the carburetor are dirty or have failed.

Typical fuel system
Fuel Line Replacement by
  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs to help with reassembly. HTH

Dies at full throttle.

Has it been standing for a while?
Few things to check.
1: Fuel filter in tank. Use a piece of bent wire to hook the filter through the filler hole and pull it out and swap it.They get gummed up with oil if they have been standing.
2: Fuel hose. Even the tiniest pinhole in the fuel line will cause exactly the problem you have.
3: Many chainsaws have another hose that goes from the crankcase to the carby, this is the "pulse line" and is just as critical as the fuel line.
4: Although one tuning jet is marked "H" for high speed, & one is marked "L" for low, at full revs they both deliver fuel, see if you can richen ( turn anti-clockwise ) the "L" jet a bit more and try that.

Please let me know and give me some more info, I have all confidence we can nail it.

2004 Jeep Wrangler Rubicon stalling out

I've had this problem on vehicles with 70k or more miles on them. Symptoms include rough or uneven idle and dying. OBDII showes no codes.

Bad fuel, vacuum leak, low fuel pressure, carbon build up, inoperable fuel tank ventilation, poor grounding, low voltage, intermittent relay contacts are possibilities.

The simplest and mostly likely problem is:
Carbon build up inside the butterfly. With the engine off, pull the intake off. Use injector cleaner and a shop rag to clean the intake throat where the butterfly is. Use a plastic or wood handle to hold the butterfly open to get both sides cleaned. If this doesn't clear the problem, check for vacuum leaks, loose hoses etc.

Check fuel pressure and replace the fuel filter if it's low.
