Sorry if I am jack-a&&ing this thread slightly but my question runs along the line of his work being done..
Ahhh, why not just run it with the vaccume portion disconnected or remove it and tack weld the part that moves from vaccume? I am running a 440 with the vaccume hose disconnected / removed. wonder if that is not optimal.. Is the mech advance not enough, or come in all at the crazy wrong time? does the mechanical part not suffice?
Maybe the mechanical advance comes in all at 450 RPM starts pinging, and comes out at 1500 then the vacume kicks in?just kidding :thumblef:
