I'd put a vacuum gage on the intake manifold and adjust the carb to get the highest vacuum (15-20). How do I adjust the carb to change the vacuum pressure? I have a 2 barrel carb.. Plug the vacuum gage into the nipple thingy front of intake where your air cleaner vacuum hose plugs in. Run the car til warm and adjust mix screw/s in first until engine speed slows/vacuum on gage decreases, then back the screws out until vacuum is highest, just before reading drops again.
It will also tell you if the ignition timing is off. Set your timing at 12 deg., dwell at 30. 12 degrees before 0(TDC) or after? Also I am new to these points distributors, how do I know set the dwell, I know its an Allen key screw inside behind the dwell cover but how do I know when its at 30 Need a dwell meter, run engine, observe number, and use Allen wrench thru window on ignition cap to adjust. Google some of that stuff if you're unsure. Hope this helps.
