Air/Fuel Mixture screw

(1/6) > >>

BoisBlancBoy:
Does anyone know what direction, tightening or loosening the air/fuel mixture screw corresponds to richening or leaning it out?

1FST690:
When you screw it in until snig and then start backing it out, the farther you back it out the richer it will be :thumbs:

BoisBlancBoy:
Hey guys, I just ran my rig on a new plug for the first time for about 10 minutes.  I pulled the plug and its hasnt darkened much at all, so this means running lean right?

So I already have the air/fuel mixture screw out 3 turns, should I go half turns out until I get the perfect chocolate color?

BoisBlancBoy:
Alright guys since I got impatient waiting for an answer this is what I did.

I changed the mixture screw and ran it for at least 10 minutes each ride on settings of 2 1/2, 3 and 4, with no color left on my plug.  I also set the mixture screw at 2 and the machine wouldnt even start.

So I am at a complete lose right now.  Whats the deal?

Could this mean I am not jetted large enough?

Flynbyu:
What are your jet settings again?
