Spark at coil and distributor but no spark after plugs installed and crank at key

All,

I have noticed that it only feels bound up after I try to add gas to the carb. This afternoon after having it sit all night I cranked from key and it cranked just fine, after I added gas to see if it would fire it started acting up.

Heading to the auto store to get a piston stop now to check TDC.
