Engine / Re: 22r overfilling with fuel! WHY?!?!
« Last post by jdurango on Today at 08:52:52 PM »I rebuilt a friend's FJ40 carb a few months back and Hanes/Chiltons and the instructions included with the kit all had the float spec wrong. At what they suggested, the float never closed. It took a few tries to get it adjusted right. Worth checking. Also, with the carb top off try blowing into the fuel inlet gently to make sure the float is actually seating the needle, and there isn't some defect stopping it from sealing.
The only other thing I can think of is too much fuel pressure, if it's too high it will blow past the seat. Your gauge and regulator seem to rule that out.
Your pickup just started doing this randomly one day without having touched anything prior?
Thanks for the advice! I'll try lowering the float.
I purchased it from the previous owner behaving this way. Apparently he got it from a friend behaving this way.
The dude I bought it from did head gasket, new distributor, wires, plugs, fuel pump, filter, and a few other random things before throwing in the towel. He told me he pretty much narrowed it down to the carb and a rebuild would probably fix it. Rebuild did not fix it.
Worst case, if I can't figure this out, I'm gunna rip all the stock stuff out and go Offy intake + Weber 32/36. I'd just really like to get it running as stock, especially after all the work I put into the carb.
