Installed the plate today and ended up with a rough idle. The plate is above the gasket and is sealed up good. Seems to be a rat-a-tat-tat at the plate.

Do I need to readjust the idle mixture? Up the idle RPM? Rough at 650 and smooths out at @800.

To correct myself in the initial post, I do have the PCV at the valve cover to the front of carb. I did'nt know that was an emissions piece.

14 degrees BTDC initial advance with timed vac.advance. The full time vac. and the rear vac. port of the carb are plugged off. Edelbrock 1406. Super unleaded 93.
