1 have a 1989 LT80 that I am ready to drop it off a bridge. I just put crank case seals a new top end and new guts for the carb. Well once all put back together it fired right up. Well today it would only start and run with the choke on and now I'm pretty sure this top end is locked up. LT80 I have been reading all your threads you seem to be the man at these. Will you please help me I'm going freaking crazy.

 

Sorry, I don't go to this place in the forums.
If it's locked up, it's from fuel filling the cylinder.
Read the threads on on/off valves and letting the carb run dry?
