Ha ha...I just caught this thread. Mine made around 80-100 passes in 9.90 form last year, as well as lits of street driving.

Still learning, but something happened and it nipped the piston. Either the plug damage, too lean, or too much boost. I'll take the blame for the tuneup, but it wasn't the parts fault.

Just about back togetter with a new slug ready for BRACKET RACE season and terrorizing the neighborhood.

Mag'd the cast crank and checked it for straightness...good to go!
