No matter what I do my plug can't be judged,white and dry,n-t carb, I have jetted all the way to a 74mm jet still white.. I did just replace the head gasket and no leaks(slant head ) plug pointing towards carb. I did the carb. Cleaner spray and found leaks at the seal behind magneto mag. Installed new seal re- checked ok. Found leak at top of carb. Fixed. At this point there is no more leaks, it's a raw motor,5th gal. Of gas 50to1 redline oil, very lost at this point. Prior to replacing head gasket plug was always wet with gas very little color, what to do next?? Anybody out there had this problem? Thanks...
