Try an old school remedy. Your 62 has had long periods of sitting without running one could presume. So its valves or rings that could be caked up or frozen.
The old school method was to pour a quart of ATF down the carb of a up to temp engine, opening the throttle so it doesn’t stall. Then take your car out on the highway for a long drive accelerating hard to blow the carbon out. Hope you don’t have close neighbors!
Second and more modern method is use a can of MOPAR top end cleaner. Many guys testify positively about this with before and after pics posted online.
I have done both and had very good results! I think the former will soak into the piston rings a lot better, but I have no proof.
