I need info on carb ajustment screws for model 20611R

tschron, is it you don't have a tool to fit the adjustment screw? Or are you wanting to know how much to turn them?

I need to know how much to turn them.

Hi,
On newer machines it is lightly seated on both screws and approxiamately 1 1/4 turns out. Final adjustment is done after starting and bringing the machine to operating temperature. Two carbs were used on that model, so it could vary a bit.
Parts manual is at:
