Hey guys, I have found a couple threads on this issue, but can’t find a definitive answer. My saw runs fine up on the high side. Revs out and four strokes perfect, but if you let off the throttle it dies immediately. Here’s a list of what I’ve done.
This is my original ported 371xp buildoff Saw from 2010.
Since then Randy cut the squish so I could do away with the base gasket. It ran good for a couple years and I robbed the carburetor off of it for customer Saw. I then upgraded it to the 372xp xtorq carb system. That’s when this trouble started. It has new;
Spark plug
Fuel line/filter/impulse line
Tank vent
Walbro Carb/intake
Ignition coil
Good pressure and vac test
I saw where people were having trouble with the Chinese carbs but this is a Japanese Walbro. Looks like some folks have bought the Tilly carb with pretty good luck but that was an old thread and that carb is only $12 dollars? Seems like it’d be hard for a good carb to be made for $12? Don’t get me wrong, if it’s what I need I’m all for it, but it just seems little cheap for a good carb. TIA fellas!
