Our '65 Cherokee seems to like 2 or 3 shots of prime before cranking, with
the primer left out during cranking. When the engine catches, slowly put the
prime in. I've tried variations with the above yielding the least cranking.
We do have Tanis heater and are hangered in a "heated" (read at least above
freezing...) community hanger.

My experience with starting non-injected Cherokees is that you do best
to pump the throttle while cranking instead of worry too much about
priming.
