Guy,
One of the methods of checking for a correct high needle with older 3w twins was to look for a little smoke on accelleration. No smoke equalled being lean on the high. A rich low needle nearly always shut them down when you cut the throttle. Good engines just the same.
Pat, thank you for your help. I feel I have the engine running pretty well now and will see how it flies tomorrow. I was too lean on the top end. You're right, it seems to like to smoke slightly in it's sweet spot.
