leaking gas

[Tommy053]

..... it seems when i add gas to tank , it comes out primer bulb hole.

Bulb seems ok, but after inspection the air cleaner gasket is bad, would this cause the problem mentioned or are there other problems ?

THANKS !!

Is this a water pump, generator, pressure washer, lawnmower, trimmer, edger, tiller or something else.

We need to know what kind of engine you are working on with model number so we can see what it looks like please.

The float valve is leaking. You will need to remove the carb, clean and install a carb kit. this model most likely has the rubber valve seat that will need to be replaced. Just don't get any spray carb cleaner around the new seat because it will swell and then crumble.

wellllll, i tried, not a lot on this simple carb to do. I changed the needle, the seat, etc. blew out and cleaned, re-did with new parts........ put back together.....still gas runs out freely out of the primer bulb............ at a loss.

thought i did good, but....... apparently NOT

any more ideas ? it can't be this hard.......?????

thanks, anyone

Everything I have read about this problem leads to a gasket leak. Check to make sure you put them on correctly and tight enough.
