Alright, had to make up a pointer because of the old damper/new timing cover mismatch. It was tuned by ear to this point, and not really run hard.
It was at 13/33*, ran it up to 16/36*. I didn't feel like throwing another bushing in it to give more advance, and figure with the heavy car/small cam/tall gear it can use a conservative tune.
When running before, it did have a definite surge to it when going 3/4 throttle and getting up over 3500rpm, that is now gone. I thought it was going to be carb, but wanted to get timing squared away. Happy to find the "surging" was timing related, but surprised that just 3* would cause it. Timing is in at 2700rpm, so it's been at full advance when this occurs.
Going to start on the carb now, setup the idle mixture and that's it to this point....runs ok but can definitely use some tuning.
