is compression at least 125 per cyl. poss t/b is off
Spray a little carb cleaner in intake will it try to run, WITH RUBBER INTAKE TUBE REINSTALLED AND TIGHT? iF it was running before head work, it is either out of time or has low compression, since you know for SURE spark and fuel are ok!! That's IT!!!
