I finally got it to idle around 1100 w 18 degrees advance. However, it doesn't want to run very well. Took it for a drive and it was not transitioning well at all and didn't want to run very smooth. I'm concerned that I have a vacum leak somewhere, but have taken the carb off, put new gaskets between the throttle plate and turkey pan, and turkey pan and intake. The other thing I was thinking is that if the vacum is too low at idle, then the Power Valve could be opening and causing it to go rich, thus the need to open up both the primary and secondary plates. Don't know so I'm limping over to a local carb guru tomorrow to see if he can work some magic on it. Hope it's just a matter of getting the screws set right.
Thanks!
