Hi,

Great Forums.
Have learned so much.

Not too mechanical, so if anyone could walk me
thru this, very specifically, would be appreciative.

Have a Tecumseh engine on a 22" Toro self propelled mower.

Took the Carb apart to clean it, but I think an adj. "might" be necessary upon re-assembly.

The Carb bowl has No adj screw on the bottom of the bowl.
Only the screw that holds the bowl in place is at the bottom; possibly has an air vent thru the middle.
Not meant to be adjustable.
*Might as well also ask: is this an air vent, and what is it for?

But my main question is the adj. screw near the top of the Carb.
It is horiz. oriented.

What is it for ?
And, how do I adj. it ?

Sr. Citizen now, very, so step by step would be great.

Thanks,
Bob

The screw you are talking about is your idle speed control. Unless you have an older unit there is no reason to change the setting.
