Hello,

how many turns maximum should be unscrewed the idle screw?

I ask this to have a reference mark in order not to lean too much the engine when it idles.

From the starting point of 1 turn open I unscrewed the idle screw progressively untill a 3-1/2 turns, and the rpm still seems stable (according with the manual if the engine is lean at idle, rmp should increase). I don't want to exceed on leaning it.

Thank you
