I'm slowly making headway with the way my engine is running. I pulled the intake off again to inspect the "O" ring that the "Auxiliary air pipe" goes through. Seemed to sit pretty worn so I replaced the ring with a similar one and coated it with oil in hopes of it to expand while it's in there. Upon reassembly, I noticed there are sparks flying around where the cap touches the mixture control unit. To fix this I just unbolted and lifted the unit up a bit-and I got my cylinder back to firing. QUESTION: In the book it mentions that the air adjustment screw is supposed to be fully seated along with the 2 balance screws-are these the brass screws the book is talking about? It is idling much lower now, and while holding an RPM it is much smoother but still a little crackle here and there. While idling it still vibrates like hell. Another question-when the book says the rockers are supposed to be "on the rock", that means that the rocker is supposed to be on the top of the lobe right? -Dani B. #5003-almost fixed!
