Hi Anonymous, check your intake seals and plug color, should be a light tan color, also check to make sure your accellerator pump is working, drop the bowl and check for contaminated or clogged jets, proper float level, depending on plug color you may need to re-jet. This of course assuming that your plugs and cables and timing are up to spec. Good luck

SOURCE: bike is stalling

Your going to have to determine if its an electrical problem or a fuel problem. Could be bad plugs a loose wire, misadjusted carb or contaminated fuel or a pluged fuel line. and actually a few other things including a bad piton ring. I would start with the cheap and easy stuff. Drain the fuel tank, clean the fuel filter......see if that helps

SOURCE: found a fixer upper harley that a family friend I

An 82 model Harley has the Shovelhead engine in it. These are good engines but they are aggrevating in that they are not as reliable as the later Evolution engines. I know a lot of people that have them and get good service out of them but they have to do their own work. Most Harley shops will NOT work on them. The reason is that they no longer have parts for them. You can get parts but they're aftermarket parts and sometimes don't work as they should. Most of the parts are made in Tiawan. If you find New Old Stock parts, they want a very high price for them.

If the bike has an aftermarket carb on it, it's probably an S&S Super "B" or Super "E". The original carb was a Keihen "butterfly" type carb, not the later version "CV" Keihen carb.

In short, the old shovel will give you lots of miles of riding but you must be prepared to do a bit more work on it than you would an Evo model. The old Shovels do have a good sound to them as well. It's a good bike for a person that doesn't mind getting his hands greasy every once in a while. If you don't want to do your own work, look for a good Evo or Twin Cam bike.

SOURCE: Im trying to find out

They go in the accelerator pump on the bottom of the float bowl. These are the check valves. Turn the float bowl upside down. There should be two screws left in the accelerator pump plate (one of them holds the float bowl to the carb body). Remove these two screws. Underneath this plate, you'll find a diaphragm and a large spring. Over towards the float bowl drain plug, you'll see two hole. One hole is deeper than the other. The deep hole is closest to the drain plug, drop the small spring into this hole and place one ball on top of it. Put the other ball in the other hole. Now, lay the diaphragm on float bowl over the accelerator pump well in the float bowl. Put the large spring on top of the accelerator pump diaphragm and place the plate over it. Work the plate around to seat the diaphragm in it's groove and install the two screws.

For a better view of what you're going, go to S&S's website. Click on "Tech Info", click on "installation instructions", and select "fuel systems". Look of instruction sheet #51-1012, installation instructions for E & G "shorty" carburetors. Download or print out the instructions which will include a complete parts breakdown, tuning instructions, everything you ever wanted to know about an S&S carb but were afraid to ask.

What is carburetor setting on a2.3 chainsaw


There is no fixed carburetor setting on these engines, just two screws to adjust low-end and high-end operation. Special tool may be required, there are about a half-dozen screw head standards. Check eBay for tool. Get the engine to run and idle fast (idle adjust) so it doesn't stall, adjust low-end screw so that engine doesn't hesitate or sputter when accelerated. Adjust high-end screw to run fast and smooth on full throtle. Readjust idle to normal.

1980 Suzuki Gs450L won't start. I stalled out pretty bad in 4th gear and it won't start back up after. Bike won't even crank over, just makes a clicking noise. Any ideas?


pull the plugs then crank motor you may find one cylinder full of gas and that will keep it from cranking, if it cranks without the plugs allow it to dry for a bit , make sure plugs are dry then install and hopefully GO!

Throttle position sensor and or the fuel pump are bad. Throttle position sensor is pretty cheap and easy to replace. Fuel pump is a pain and a little more expensive.

How do I adjust the carburator?


There are two needle screws that can be adjusted to make the engine run properly. Be certain that the carburetor is clean and the diaphragm is in good condition, and the fuel is new. The two needle screws mentioned above should initially be adjusted at one turn open from turned in all the way (lightly seated). Each of these needle screws performs different functions. One is for idle and throttle response (this screw is marked "L" and the other screw is marked "H". L and H are marked on the carburetor body and also on the plastic "shroud" near the adjustment screws. These screws are not interchangeable, being foolproof since the thread sizes are not the same. When properly adjusted the low speed screw (L) allows the engine to idle properly and throttle response will work properly. When the high speed screw is adjusted properly the engine will have correct power at full speed. Adjust the low speed screw so that the engine idles and when you squeeze throttle all the way to wide open the engine should not hesitate and should come up to full speed and when you drop the throttle it should idle nicely without stalling. Now adjust the high speed screw. Hold throttle wide open, holding it there while you adjust the high speed screw. If this scares you (be carefully so that the spinning chain does not cut you!) you may adjust the high speed screw at idle, turning it just slightly in or out. The high speed screw should be adjusted so that the engine does not run clean at wide open throttle but sputters slightly, slightly adjusted open from running clean to slightly sputtering. When under load (cutting a log) the engine should run clean. Good luck!

check for the pinched vacuum line at the carb,, sportys are hard to locate because they are tucked in way behind , it ay have come disconnected, unless there is a load on the motor it will idle fine, add a little load and you get the feeling no fuel is getting through unless you rev it up

I tried using quick start on it, but all that did was make it sputter a bit, so I am assuming that the fuel is not reaching the cylinders, anyone have any ideas?


1) Check for spark remove one of the plugs, connect the plug wire to it and ground spark plug base to a good ground , such as the cylinder head , position the plug so you can see the electrodes , crank the engine over , a fat blue spark should be evident. 2)If the spark is good , check for one or more of the following possible malfunctions 1) Obstructed fuel line or filter.2) leaking head gasket(s)3) low compression. If the spark is not good, check one or more of the following a) Weak ignition coil(s) b) Weak CDI unit. c)Loose electrical connections. d) Dirty electrical connections. e)Loose or broken ignition coil ground wire. f) Broken or shorted high tension lead to the spark plug. Difficulty in starting. Check for fouled spark plugs, Improperly adjusted choke, contaminated fuel system, improperly adjusted carburetor,weak ignition unit,weak ignition coil (s), poor compression

Ryobi lawn trimmer keeps stalling out. I have


If it is a relatively new unit it should have the carburetor adjusted after the first few hours of use. If it stalls upon accelleration the low speed adjustment on the carb needs to be opened a little bit. If it runs a few minutes and then stalls it could be the high speed jet needs to be opened or the fuel filter is clogged.
