Tclerderman recommended I try the old original intake. So I resurected it from the junk pile and put it on.Same problem. Tried 2 different carbs. Both act the same.Has a really bad flat spot unless I leave the choke closed a little and doesn't like to restart after I shut it off. The really puzzling part is the timing Why does it only want to idle decent when I have it so far advanced that I'm up to the triangle on the flywheel with my timing light. When I try to get it on the ball the idle drops too slow on the verge of stalling? Anybody know how many degrees advanced I am if I'm on the triangle?
