Question: I have a Plus4BTT with a few gallons on it and was broke in well. Heat soaked and tuned if the engine dies it's hard as hell to start. It will not start until it sits for 5min or so. Heat soaked it's running about 220F or so in 90F weather. New plug and doing the same thing. Seems to have good pinch still when heat soaked. Running 20% Byrons. Please help.
