Darrell,
Due to the way your Tillotson carburetor has had the pop-off pressure set, the needle adjustment and the track performance will vary. The following is only a starting position for the needles. From this point on, track tuning will be necessary to dial in the Tillotson that you have. Low side needle out 1 � turn, high side needle � to 1 turn out. If your carburetor won't dial in somewhere in this range then you will have to change the pop-off pressure.
Regards,
Bruce
