Just pulled the plugs. 3456 plugs looked fine. 1278 plugs were allitle black. i compression tested the motor and the lowest it had was 110 and the highest it had was 130. pulled the valve covers and nothing is a miss there. cranked her over and the cam seemed like it was still in good working order.

around the factory timing settings in park it just pops out the carb as you rev it. throw it in gear it does it worse.
