Was dwell at 30-32 degrees? if yes then can time make sure vacuum hose has NO vacuum at idle. Also make sure weights in Dist are free grab rotor you should be able to to move and it will return. Time at 4 deg ATDC these motors run better at that setting.
Pull coil wire hold 1/4 inch from intake crank good blue/white spark? Hook up vacuum guage what is vacuum ?

Well not 180 suspect engine was on exhaust stroke. pull no. 1 plug turn engine by hand. Put finger in plug hole rotate when you feel air escaping that is comp stroke. set crank on 0 TDC see where dist is pointed. If good next look at rotor turn engine counter clockwise till you see rotor move how many degs.? this will tell if chain is out
