Air Screw Question

[pmieras]

So i've noticed that most of the time the air screw is adjusted to 1.5 - 2 turns out. Does anyone turn it in to make it rich? Say to 1 or 3/4 turns out? Just wondering cause I notice most of the time it's set 1.5 -2 turns out.

I normally run mine between 1 and 1 1/2.

Me, too

What type of problems would you see by running it too far in? too rich? Does it affect across the entire throttle range?

If you find that you need more than 2 turnS out on your air screw, you are in need of a bigger pilot.

If im understanding this right:

Air screw out = more air = lean

Air screw in = less air = rich

 

Is it only at idle or across the whole throttle band?

Yes, clockwise is richer couterclockwise is leaner.

 

Here is a good read about jetting. Q#10 is focused on air screws. http://www.dfn.com/agservices/jetfaq.html

A Clymer Manual will answer most every question you can think of.
