Have you tried carb cleaner spray? Its sounds simple, but it works on my chevy's. Also there are some you pour into the carb as well as your tank. Try the simple solutions before you dive into disassemble mode

Does it run better on full choke, but only goes slow? I bet I know what it is. On the top of the Carb take off the cover, there is a rubber diaphragm in there, I bet it has a hole in it. When you push the throttle , that creates a vacuum, which lifts that piston to give it gas, otherwise it just gets air, starving for gas, it just kills.You should use an impact screwdriver (ya hit with hammer) to loosen them screws! That soft *** metal strips like its lead!

Definitely check the needle and seat. It sounds like the fuel is rising too high. If the needle is the type with a rubber tip, it may need to be replaced because they don't stand up very well to the ethanol that is added to gasoline these days. Safe riding.

SOURCE: carb acts like its choking out

If it wasn't choking out before you cleaned it, you will need to break it down and check your work.

When off gas is leaking


1. remove the hose from the carb and see if the petcock is shutting off the gas and if not clean, repair or replace the petcock.
2. look in the tank and see if it has rust in the tank even a small haze of rust as rust will cause the needle and seat to stick in the carb and make the gas leak. If the gas tank has a lot of rust it may need a tank rubber liner kit added or even a new tank to stop the leaking.
3. if the bike has been sitting for a while it may have trash in the fuel system(carb/petcock/tank). Rust or any trash can cause a leak. Properly clean out the carb and fuel system and add a new filter when done.
4. Improperly adjusted or bad needle/seat or float in the carb will cause continual leaking. Replace the needle/seat/float and adjust the new one when installed. Check your service manual for float adjustments.

Gas leaking from carb


Most likely cause is float level too low, and/or punctured float/worn needle/seat valve in carb.

Gas from the tank runs through the engine (when the motor is off)


Hi and welcome to FixYa, I am Kelly.


You can fix this yourself.
(Turn off the fuel selector)
Remove the carb float bowl nut and bowl. Note the gaskets upper and lower. Remove the float pin retaining the float and drop the float and float needle together.
Briefly turn on the fuel selector and then back off. You are flushing debris from the float needle seat. It is a good idea to use carb cleaner to ensure that the float needle seat area is clean.
ALSO spray carb cleaner into the threaded area where the bowl nut attaches. Your cleaning off the metering jet orifice up inside the threaded area.
INSPECT the float needle itself. The rubber tip should be tapered and pliable. If there are any nicks cuts or debris on the end of the needle first wipe it off and determine if you need a replacement float needle.

Reinstall float and needle ensuring you have the float pin properly installed.
CLEAN the bowl NUT along with the float bowl. Then reinstall the the float bowl. 2 gaskets upper and lower must be properly seated.

Turn on the fuel selector...
Test for leaks.

This should fix the leak but... if you still have the problem and did not change the float needle and seat. Change them. The float needle seat can be difficult to remove. I find that air in the fuel supply manifold fitting will blast most of them out but... sometimes I have to use a drill bit the size of the hole to cut the rubber material and then dig it out with a scribe or jewelers screwdriver. Just make sure to clean the hole with carb cleaner before installing the new seat. To install the new seat... reverse the drill bit using the flat chuck driven end and press it into place. Works great!

Thanks for choosing FixYa,
Kelly

This is for an 1979 Honda CBX. I installed new float needles and seats. Also, I adjusted float levels to factory specs. All carbs are still flooding.

Geting fuel to carb. Will run with starter fluid, but dies immediately when I stop the starter fluid.


sounds like the float and needle are not working proper. The float :floats in the gas bowl raising and seating the needle into a jet hole. If the float has quit lifting the needle out, then no gas will come through to reach the carb. This is why you engine runs with carb fluid because you shoot straight into the carb. Try replacing those 2 and clean the carb. It's a simple task and cheap fix.

if its coming from the carbs then the carbs will need to be removed and inspected and cleaned internally. Its most likely a needle seat for the fuel level. A real small piece of varnish may be preventing the needle from seating allowing the fuel to continue to flow.

Motorcycle dies while riding,like gas is cut off


Most likely your high speed needle valve seat has dirt in it. Try removeing the bowl and cleaning the Main Jet.

Carb and valve adjustment


Dear Craig,
Presuming that the carb is clean !
It seems that you have either set the float level incorrectly, or allowed the needle to become jammed. The float bowl should a little less than 3/4 full of fuel when the fuel is shut off by the needle and seat.
Check that the needle and seat are working correctly by blowing in the fuel pipe, and then closing the needle by hand. Check that the flow is stopped when the needle is fully raised.
The needle and seat do need to replaced from time to time, but generally last well.
If the needle and seat work, then look at the float level.
Further check to see that the floats are not filling with fuel. If this is the case, then the floats will have to be replaced as most repairs are only temporary.
When the floats are fuel logged the needle will not be raised and fuel flow to the carb will be continuous.
