Thanks, will try that on the next tuning session.

How much lower? It has "HP" float bowls with the large sight windows, and it's about 1/3 up the glass at idle. Fuel pressure 5 psi.

I can't turn the screws in any more, it's about as lean as I can idle it now... shruggy That's why I put a little more on the secondaries (2 turns) than the primary (1-1/2).

Could I go one size smaller on the mains (to #72)? work
