Need tuning help on 340

I dont think you can read the plug from 1 quick pass usually takes 3-4 before you start seeing color.

I had wondered about this, whether i should put several passes on the plug first.

I am fortunate as they just built a new interchange about two miles from me, and just past it I'm in the countryside. A quick right turn and I'm on a 2-lane seldom used side road where I can see anyone coming from either direction. Over 1/4 mile straight away. Nice.:burnout:
