Did you pinch it while the motor was still somewhat cold? The rpm's should only go up a lil like 500 or so. If it goes higher then lessen the gap. If doesn't raise at all open the gap.

Now with the hsn at flush or near to it with the motor still somewhat cold, pinch and see how long it take to kill it. Ideal is seven seconds. If less then seven richen lsn, if longer lean lsn.

With the idle and lsn set put it on the track and run with the Hsn needle near flush, now I like to run two tanks, and on the bottom half of the second tank I start to lean off the hsn 1 hour at a time till I have a nice exhaust note and smoke all threw the rpm range.

With the fuel lower in the tank you won't have to worry about going lean as tank empties for you are already there, when it's full it will be slightly richer but not enough to hurt performance.

This is basically Grizz1's tunic method, I only changed the half full tank hsn tuning.

Sounds to me your idle is wide with rich lsn and lean hsn. One needs to learn to only move one needle at a time test and try the next needle. If you adjust booth needles all the time one might be set right and the other off, then when booth are moved one is right and the other is off, so your always chasing. With the long lsn once it's set you hardly even have to touch it, just move the hsn.

So I say set the idle and lsn and then don't touch em and do all your tuning with the hsn.
