As i said earlier I changed to the old float and cleaned everything out again. Wanted to see how it did after all that. No difference. I went ahead and went through the adjustments just to see.

Mix Screw Adjustment (Rotations out from seated), RPM, VAC (in Hg), Notes

4, 600, 20
3.5, 600, 20
3, 600, 20
2.5, 600, 20
2, 630, 20
1.5, 680, 21
~1, 750( corrected to 650 via fast idle screw), 22 **Returned here (best vac)
.5-.75, ---, --- (Vac and rpm dropped off, very rough idle)

Still boggs out trying to get it going. When I first started it up I sprayed a lot of carb cleaner and no change in idle. After it was hot, I did get a slight reaction to the throttle body gasket on the back side. Could heat/warpage be causing a vacuum leak? The throttle body flange isnt perfect but I would be surprised if thats the culprit of the bogg situation. I may take it off and get a real flat surface to wet sand it on. Just speculation at this point.
