Ya I already went through the procedure for setting the throttle position screw. ItÆs a bit back in the thread.
And it did seam to fix the little surging thing it was doing.

But itÆs still idling up and advancing timing when it shouldnÆt. And I have still to figure that one out.

Anyway IÆm going to drive it with the weird timing advance problem for a while and see what it dose at 200 mile or so. Then IÆll start tackling the problem again.

thanks
