Thanks again guys.
We finally got back to the Nova. I took the carb apart at home and cleaned/ blew it all out. We put the carb on and set the timing to 36# at 3000. The headers glowed so we put the old HEI back in ran it up and set the timing to 36 and the header glowed!!!!

We took the carb off and went to put the spare on but were missing a plug for this carb so I said lets put the 1st carb back on and see what happens.
Well low and behold everything worked fine??????????

So with the throttle plates drilled with a 1/8" hole the plate is above the idle slots and idling at 1100 in neutral, dropping to about 800 in gear.

What if we drill another 1/16 hole in each plate or would you recommend opening up the 1/8 hole to 3/16? Thanks, Henry.
