I was told te engine was bored over .030 and stroked. Has a quick rev from 1000 to 3000 with hardly touch oof pedal, Was dumping fuel and have tamed the carb a good bit and now is burning fuel better, but noise persist.
I described noise to my brother who said I should correct valve lash before any more drastic measures are taken. Engine was rebuilt 3000 miles ago, but nothing done to it since. Brother talks to fast and makes it sound to simple.
