View Full Version : Stupid Question

Hello,

Excuse my ignorance, but in the repair manual for the AS model carter carburetor it describes screwing the idle screw into the carburetor body until it "bottoms out lightly" then it says to "rotate the idle screw outwards a full turn."

The question:

What the devil does "bottom out lightly" mean and is there a more accurate way of adjusting the idle screw?

Thank you

I would guess when you first detect contact with the lightest touch...

That method has worked well for years.

They want you to screw it all the way in, but not so hard that you'll damage either the needle end of the screw or the seat in the carb body.

Forgot to say, that after you get it running, fine tune the idle with a dwell tach or whatever you have to do that with.

That is a good point to reiterate...

Set the points (dwell) first.
Set the timing second.
Set the carb idle mixture screws third.
Set the idle speed screw fourth.
