Carb leaking gas?

Rammunition360 · Jul 28, 2008

im new to carbs...im 20 and this is my 1st carbed behicle besides chevy TBI which i guess doesnt count...but i am leaking raw fuel from the front of the carburetor and its not coming from the fuel filter...i had one unplugged hose so i ran it to the nearest hose plug and it wasnt even leaking from that...maybe a gasket???

Try drying it up real good and then starting it and watching to see where the wet spot starts.. Gently tightning the screws on the gaskets usually stops any leakage from them...BUT there shouldn't be fuel on the gaskets unless the vehicle is on a rough surface and the fuel is sloshing around..

If not the gasket, it could be the float is set too high or is leaking and allowing too much fuel into the bowl.

do i have to take off the carb to investigate this? because i will need to know the info on that then haha...i dont want to mess up any choke or throttle things

Ramm Since you ask such a question... I would advise you to seek professional help.. Or at least a friend that knew something about carbs..
The most that I think YOU should do is to take the air cleaner off and try to gently tighten the screws where the gasket is.. Outside of that you might need a friend that has taken a carb apart before to assist in the endevor..

Odds are it's the accelerator pump. It's simple to put in another one. It's right on the front of the carb. 4 screws and your done. They go bad. It's fairly common and cheap to fix.

Your thinking about something different. The accelerator pump is just a diaphragm on the front of the carb. It's about a ten dollar part and takes 15 mins. to change.

It's easy to figure out if it's the accelerator pump. Just manually advance the throttle on the side of the carb. and if fuel comes out of the accelerator pump ( the front of the carb ), it's bad.

You might want to ask someone who's a little more familiar with carburetors to help out a little.

Any questions just post or pm. Good luck.

oh ok so it attaches "to" the carb...i was referring to removing the carb and rebuilding haha ill go try that accelerator pump

Rammunition360 · Jul 29, 2008

ok it only leaks out when the engine is running and it is leaking from the peice on the front attached to the throttle cable

go to the parts store for a accelerator pump.i bought one two years ago for $12.when you see the part it will make sense.

take your time,pull the screws out,carefully remove the cover,there is a spring in there.then change the old diaphram for the new one.easy.

yeah i already priced it at $11.99, its 4 small bolts (bottom 2 kinda tricky to get to) then exchange for new one...gotcha, and thanks
