#2 cylinder not burning hot?????

well if the compression is good that rules out rings.
you have ruled out electrical. (i'd still put a brand spankin new dist cap on if you have one. )
i dont think an intake "leak" but maybe... if it was really sucking air or something.
it cant be a cracked head around the valeve seat because the compression checks out.
maybe the intake port is blocked by a piece of gasket? it would still get some air/fuel and would fire though.
unless the valve is stuck closed i dont know bro
