Have you adjusted the air mix screws? They are on the sides of the carb. There is a great pict of them in the photo group under technical. You have too drill out lead plugs. Use a small drill and a pick to get them our. I beleve 2 1/2 turns is what you need but you can adjust that. Stock I think they are 1 1/2, but if you turn them in all the way gentley and count the revolutions and add to that as you back them out. Hope this helps
