I've got a chinese made Yamaha knockoff. Aside from the lockup, BTDT.

I think the off timing could have a little to do with it, but not everything. Never overlook the spark plug, no matter how new you think it is.

Aside from the carb itself that I finally replaced, mine was sucking air at the boot between carb and jug because the boot was cracked. Didn't see it setting still, but as you bounced around, it would flex a little and cause the screwups. Once I found it, I smeared gorilla glue all around the boot and ordered another (haven't put it on yet cause the GG is still holding).

James Rump;

What do you suggest for a plug brand? I go through NGK's like candy.
