OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Honda Engines GXV120(?) Carb - What does this part do exactly ?

Hi guys,

Long story short, I sold a cheap mower which had a copy honda engine. Mower works, I know it does, I used it myself, never had an issue and would never sell it as working if it didn't

Customer, after a couple of days says when "fuel switch" is 'ON', it "pisses" fuel everywhere and won't start.. I'm just going to refund to prevent any issues.. though the question that brings me here is..

What exactly does this part of the carburetor do? I believe it's a Petcock(?) but is it used to turn fuel ON/OFF? I've always just assumed it was a choke that you turn 'ON' in colder whether to help start the mower, then turn off when started/warmed up?




If left 'ON', can it flood the engine preventing the engine from firing over ?

I probably should know this.. though still learning some parts of an engine/carb.

Any info would be super.


(note: I know many people would say it's cheap "throw away" chonda and wound't bother with it.. though I don't believe in just throwing stuff away regardless of brand / make etc.. If it works.. it works.. and it does work..)

Thanks
