Engine: 48cc w/ bofeng carb, expansion pipe, bbr s1 ignition module & coil.
Drive: shift kut jackshaft low gearing.
Failure: while rounding up our turkeys, I ran it crossways over a plowed field, several ruts, and it died, now will not re-start.
Tests and checks:
Fire- measured over 12V from magneto, a significant pulse from plug wire to ground.
Have not done visual check with plug NGK BP6HS.
Magneto- checked mount. 1 screw loose. May have been a factor, maybe not. Removed mag, key is OK not sheared. Ground is good, continuity 327 ohms.
Fuel- checked carb float bowl (full) disassembled checked level ok, jet clear no debris.
Compression at spark plug feels normal.
Intake suction? I can't feel any, and it seems its pushing air OUT???
I'm lost unless ya tell me a cracked piston or crankcase might do that.
I'll let this stew a bit b4 I take it off. I do have another ready.
Hope my post a bit better than the 'won't start what's wrong' query, I've lived the other side of that question too long to forget to plug it in.
