Hi all
Got the secondary bog pretty much tuned out. Verified that the diaphragm was in good shape and that the air door opening was in spec. Gradually bent the linkage, and the bog is gone. Tires screech almost immediately.
I am still having a little trouble with the stumble. It almost completely went away with the float adjustment a couple weeks back. That was when it was 85 degrees. No longer so. Car is basically undrivable on a 50 degree morning.
I think that it is simply lean all the way around, given than the plugs look pretty horrible (pretty much no color) and that it likes the mixtures screws about 5 turns out. Car has 4095 jets in it right now. I'm going to try 4098s, which I have seen many people say is a solid starting point.
Doubt this is the case, but it a vacuum leak around the intake ports common? and how should I check?
