"Les... S/Speed = 1 1/2 turns

"Les... S/Speed = 1 1/2 turns out. H/Speed = 1 turn out.

In gear at full throttle. Slowly turn in high speed valve until engine starts to die. Back out valve approx 1/4 turn. Somewhere in that 1/4 turn area, you'll find the smoothest setting.

Idle down to where the engine will stay running. Slowly in segments of 1/8 turn, start turning in the slow speed valve. You'll hit a point whereas the engine will either spit back (sounds like a mild backfire) or it will start to die out. Back out the valve to its smoothest setting but not beyond 1/4 turn.
