JS38 Mowmentum carb question
I know this is primarily a tractor group (which has been exceedingly helpful in the past!), but I'm hoping some of the gurus can still help with a small push engine question. Engine just coughed and quit one day and would not re-start. Went ahead and changed oil, air filter, and spark plug just to be safe. Cleaned everything visible as much as possible with shop air compressor. Checked carb bowl and pin stopper for cleanliness and smooth operation and also verified clean fuel flow. All pristine. Finally narrowed down to carb (valve?) just behind air filter.
It's connected to a rod/bracket that moves it open and closed, but that rod isn't attached to anything except return spring that CLOSES it. Exactly what actuates that flapper open? I don't see anything hanging loose, but has a linkage come loose? Wondering if it's somehow supposed to mechanically connect to the "kill switch" handlebar. Used my engineering prowess and zip tied the arm in full open position and engine ran like an absolute top. Mowed all day including several full start stop cycles with no problem. Sure doesn't feel like the proper solution, though, so I'm hoping someone knows correct fix for this!
Thanks in advance.
