Hal,
I took your suggestions and went out and bought a whole bunch of jets. I had 77's in the primaries and put in 73's to start.
It is much better. Idles better now, now popping on downshifts and less black smoke.
I got a little hesitation when letting off then getting back on so I am going to try the 72's next. Suprisingly clean plugs for the over jetting.
One other thing, it idles a lot higher when the engine is hot, I tried loosing the idle screw, and it will not back down unless I force it down manually to the set screw. ??? only does it when hot
