Generator leaking gas and won't start.

Looks like it stops at spec j but the float maybe the same. I may have one at work. http://www.partsfortechs.com/asapcart/1460783-repair-kit-carb-onan-p-374.html

Look in the parts manual under carburetor kit. I’ll look to in a little while.

Another thing that can cause fuel flooding of the carburetor is if you have a fuel pump that is generating too much pressure. This can happen if the original pump was replaced with an incorrect pump that produces too much pressure. On my Onan 4BGEF the pump must only produce 3-5 PSI, as I recall. Standard automotive fuel pumps can deliver much more and the carb might not be able to hold it back.

He took some things apart. There was fluid in this plastic floater piece. Anyone know where I can get this replacement floater?

Carb rebuild, as the other poster said Float valve (needle valve) Not closing.

I had this happen on a big Dodge V8 Back in the days. Turns out it was a fuel pump problem, as the pump diaphram failed it flaked off and the flakes got into the needle valve. so the problem is very likely related to the replacement of fuel pump and filter. A bit of debris was knocked loose and got in the valve.

Carb clean and rebuild and you should be 100%.. May need to just clean the needle valve.

If I paid someone to do all that work on my generator and it came back with that problem I would return the RV and expect him to fix it for free.

My daddy always was a believer in taking a medium to large screwdriver and use the plastic handle to tap on the side of the carb in an effort to unstick the float/needle/and seat. :W

It appears that you may be able to take that carb off and clean it or replace it.

BTW, as far as a fuel shut off, I would recommend an easy install of a aftermarket valve stuck in that flex fuel line.

If the generator is exercised monthly for 45-60 minutes under load as Onan recommends, it will not gum up and any moisture in the windings or light corrosion on the slip rings will be removed.
