Idles with 1/2 choke. If open choke, or throttle - engine dies without any RPM spike. Carb was cleaned, jet is clean. When idles, there is gas in the primer bulb.


Hi, Andrew and the usual suspects are:

1. Fuel cap or fuel tank is not venting properly.

2. Fuel filter clogged.

3. Fuel line pinched or kinked.

4. Float needle and seat sticking.

5. Float level too low.

6. Carburetor bowl vent line clogged/blocked/pinched.

7. Idle adjusting screw set too low.

8. Air/fuel mixture screw set too lean.

9. Idle port, transfer ports, slow air jet clogged.

10. Slow fuel jet clogged.

Motor sat for eight yrs, cleaned carbs, motor will start but dies out , motor will run with choke almost closed, whats the solution ?


I do not have any information on what type, size or year engine you are referring to. Generally speaking it sounds like a clog is still present in the carb. Check the Main jet and the orifice leading to the small brass tube in the center of the carburetor venturi. Or it could be the idle circuit which is a pin hole or two behind the throttle plate. When you close the choke ( I'm assuming the engine has a choke plate not a primer) it will pull fuel out of the float bowl and feed the engine. So fuel is not going through the normal channels.

Your carb need to be taken apart and have all circuits cleaned and the float needle and seat cleaned (replaced) and float level set to level. Make sure you can blow compressed air through all the circuits. You can also get a welding tip cleaning kit to poke out the circuits. It most likely has "varnish" in the bottom of the float bowl still preventing enough fuel from getting to the ide circuit or the venture without assistance from the choke

01 dyna sup glide carb rebuild Idels/starts great give it throttle it wants to die/ choke out, I've checked float Shut off valve Jets/excilerater pump/float/all seem okay


Carb rebuilds are extremely sensitive to being set correctly. If when you accelerate you say it seems to choke out, slightly close the choke or place your hand a small portion over the carb to see if there is change for the better because it sounds like it is leaning out. The float level is so, so crucial for a successful rebuild. If by choking it make is take the fuel better, the float level is too low so check it again. If it make matters worse, there is a problem with the overall rebuild. You must make sure everything is clean and all airway and passages are unrestricted. A simple misplacement of a gasket can cause unbelievable issues. Use a suitable solvent to soak the parts in.

Make sure that the fuel is flowing freely from the tank. There is a screen before the petcock. If the fuel seems restricted, remove the petcock and clean or replace the screen.

Good luck,
Vinnie

Carb. on 883 sporster


How did you set the float level. Sounds like you did not get the float adjustment set correctly. It is very particular and it is critical for proper running etc etc. Carb has to be set on the throat and then tilted between 15 to 20 degrees to set the float level or it will be wrong. Greater than 20 degrees will collapse thew pin return spring, less than 15 will not set float properly on needle. Then setting must be 0.413 to 0.453 inches.

Settings for carb float level and air setting


the air screw gets turn in fully and the turned out 2 turns this will set it right for most bikes you might have to play with it either half a turn either way

When setting the float level be aware that the spring loaded bumper on the fuel inlet needle valve may have a tendency to compress under the weight of the float assembly which will skew your measurement. Before you obtain your measurement you'll need to make sure that the float assembly tang just barely makes contact with the spring-loaded bumper. Sometimes it is easier to hold the carb body at a 45-degree angle to avoid compressing the spring in the fuel inlet needle.

If you find that your measurement does not match your float level spec then you can carefully bend the float assembly tang to achieve your desired measurement. Be sure to recheck your work, and if you feel confident that your float level is spot on then you can reinstall your carb

hope this helps

My 190cc, no primw, no choke engine stalls after a


Clean the carb bowl out. Check for water in fuel. While the carb is open check the float for obstructions and good volume of flow.
Make sure the float height is within spec. You will need to go the BS website and get this spec with your motors model and serial number. Normally floats are good when they sit level at the point the fuel stops flowing.

Good luck and be careful!

Floats not set


Float tabs come set flat to surrounding plate, bend up to decrease level and down to raise level. Raised level too much and you risk fuel overflow on sustained inclines and too low a level and you will lean out at high revs and damage valves/piston real quick. There is no set level to speak of, but better to err on the side of losing a bit of overflow. The overflow drains from the carby via a plastic hose from just above float bowl flange.

Choke is working only has 5000km on bike and once bike warms up it loads up wih fuel and then dies out all ports are clean i tore the carb a part 3 times what should the fuel|air screw be set at.it must be...


It seems the carb/s flooding with fuel and thus it dies, try to reset the float pin and get the correct level of the fuel in the float chamber.
Standard procedure for air-mixture screw setting is u take the screw right in slowly taking care not to over tighten it as it may damage the tip of the screw.
Warm up your bike's engine and thn slowly turn anti clockwise the air-mixture screw to about 2 & a half turns and observe the engine's idling.
Before you attempt this setting(air-mixture) its better too, to replace the spark plug and set the gap to the specs of your bike's engine and check and adjust accordingly the valve clearance.
Hope this helps!
