I was going through my carbs and i dont have any mixtures screws besides the ones at the bottom of my bowls. 1st what should they be adjusted at and also there is a screw underneath my pilot screw, so do i need to adjst that one also. thanks

Your post doesn't make a lot of sense to me. Perhaps you could explain what you are talking about regarding the screw under the screw and the need to adjust it.

You have pilot mixture screws that adjust the air/fuel mixture of the pilot circuit. About 1.5 turns out if you have stock jetting.

The screw under screw thing? Do you mean that you have a #50 jet over your #15 pilot jet? How can you adjust these jets which just screw into place? They need to be tightened and they have no adjustment except perhaps if you mean replacement.
