Hi,

Great explanation, You have a blocked exaust. Either the spark arrestor is blocked, or the muffler is plugged, or you have a plugged exaust port.

The best way to figue this out is to take the muffler off and shine a flashlight into the exaust port and look for carbon build up. You should see the piston go up and down, the whole port should be open. If it is blocked, clean it out with a scrapper. Make sure the piston is in the up position before you start scrapping( to keep the carbon out of the cylinder), Then wash the carbon out with spray carburetor cleaner. Then start the engine and it should run like normal ( loud but normal). The next thing is to clean the spark arestor screen, Hold it with pliers or a vise and use a torch to burn the carbon off. Once the screen gets red hot it will cook the carbon right off.

Hope this helps

Engine will not go to high speed fuel oil mist blows out .checked spark arrestor ,muffler,exaust ports.


If the mix is blowing out the muffler than it is flooded either due to improperly adjusted carb, stiff diaghrams in the carb or weak spark. Weak spark could be a bad plug, failing ignition module, or spark ouit of time ( sheared flywheel key).
Bad fuel will also cause this symptom.

Fatboy only rode twice in 2 yrs won"t idle


It sounds like your slow speed jet in the carb is plugged. When fuel is left in the float bowl and it evaporates, it leave behind a thick gummy residue that will plug the jets. You can try running some fuel injector cleaner mixed with your gasoline but I've not had good luck with it. In order for it to work, it has to flow through the jet but can't because the jet is clogged. I'm afraid that the best cure is a complete disassembly and soak the carb in a professional carburetor cleaning solution. To avoid this problem in the future, shut off the fuel somehow and either drain the carb or run the engine until it quits to empty the float bowl. The petcock on your bike is vacuum operated and I'm not sure if it has an "OFF" position. You may wish to replace the petcock with a manually operated unit and plug the vacuum line that goes to it. This way you can shut your fuel off or turn it on as needed. Pingel makes a very high quality unit but it is kinda pricey. You can get a Harley unit for a pre-1996 model bike as well.

Good Luck

Has been sitting for a year. Won't stay running. Not getting gas. Float bowl was emptied and new fuel put in. HELP!


You will need to remove the carb and clean it. Remove the float bowl and clean the interior of the bowl and the interior of the carb body. Soak the entire carb, (with bowl removed), in denatured alcohol. Any hardware store will have it. Let it soak for an hour. Then clean it with spray carb cleaner. Spray into every hole you can find. Spray from both ends of the hole if possible, where the spray goes in and where the spray comes out. Pay special attention to the pilot jet (idle circuit), and main jet, (high speed). The diagram below is a generic carb. Please rate my answer.tombones49_212.gif

Oil blow-by out of breather/air filter at high speeds (80 mph and up)


The EPA requires that all crankcase vented air pressure be run through the engine to be burned. In order to comply with this, the crankcase vented air is vented through a hole in each head and is carried to the air filter by large hollow bolts called "union bolts". There is one on either side of the air filter element. Since the vented air has an oil mist in it, this mist will eventually build up in the air cleaner and drip out or be blown out by the wind. You should clean this buildup out of the air filter assembly regularily. If the build up is excessive, it could be due to excessive crankcase pressure due to wear in the rings or it could be caused by the umbrella seals in the center rocker box cover not sealing well. Replacing the umbrella seals is simply but it requires the removal of the rocker box covers. To get the covers off, you'll have to remove the fuel tank.

Good Luck

2008 mtd lawnmower tries to start when sprayed with carb cleaner but stops after 3 seconds


If the spark plug is in great condition, remove and clean the carburetor. This will require soaking if needed with a good solvent or carb cleaner and compressed air to blow out the tiny passages that are clogged for the idle jet circuit and high speed circuit.

Replaced blower motor on my heater now it runs without top cover install cover and it flames out


This is pointing to a bad or dirty fuel nozzle, ultimately you should replace the nozzle pay attention to spray angle and GPH rating printed on the nozzle. You can try cleaning it with compressed air and a blow gun,or carb cleaner and Q-tip and tooth pick. I soak mine in carb cleaner and use the Q-tip to clean around the out side with out damaging it, and tooth pick in case there is any obvious pieces of dirt stuck in the nozzle, then blow it out with high pressure air to finish. If you have cleaned it before in this manner it may just be time to replace it. Good luck!!

2001 ultra classic fuel injection with screaming eagle heads, when going at a high speed around 70 or above oil shoots out breather tubes that go the air cleaner and runs down side of motor. already...


Hi Berkberks, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck

Craftman 32 ccweedwhacker womnt run without choke being on


This is probably a fuel-related issue, not a mechanical one. With the choke on you are enriching the gas/oil fuel mixture to the engine. This indicates that the carb is probably set too "lean" which can cause poor idling, acceleration and even mechanical damage to the engine due to lack of lubrication esp. at full throttle. Running it with the choke on will have ill effects also. You may need a diaghram or carb rebuild kit. Check condition of fuel filter in the gas tank and the fuel lines themselves. Take the covers off the carb (paying attention to location of gaskets and diaghrams) and spray liberally with non-flammable brake parts cleaner. Don't blow out the passages with high PSI strength air and don't soak the carburetor in carb or parts cleaner....then let dry, re-install and try to start and run. The Low and High speed mixture screws can be adjusted on these. You can buy the special tool or make one out of steel brake line tubing or 22 gauge female disconnect wired spade terminals stuck on thje end of a screwdriver...or you can remove them completely (notijg how many turns it took to remove them) and cut notches in them for use with a regular screwdriver...I just think the carb needs some cleaning and minor adjusting and it may work....if not rebuild it or get a new carb.

Saw starts then dies. Changed fuel ine soaked carb


Check the fuel filter, air cleaner and muffler for plugging. Was the carburetor disassembled when soaked and did you use compressed air to blow out all passages? If the carburetor jet screws have been moved, preset them as follows: Turn both H and L screws CW to stops (lightly), then back out CCW each screw 1-1/2 turns. Start the engine and allow to warm up. Pull the throttle full on and adjust H CW until the engine speeds up somewhat but 4-stroking. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Allow to idle and adjust L CW until the engine runs fairly well, but still allows the engine to 'follow the throttle'. Adjust idle speed screw so that chain stops turning, but the engine continues to run. Hope this helps!
