Has good spark at coil wire end to ground, show firing on removed spark plug.
Compression shows 75+ on all cylinders. Cleaned carb, tried different carb. Vacuum gauge on wiper port on intake shows 7" when cranking. Verified timing, piston at top with timing plug indented.
Wouldn't this good compression indicate valves and head gasket ok. Thanks

Problem turned out out to be weak spark when cranking. Although firing on removed spark plug, apparently spark was not good enough. Noticed wiper tube from intake manifold getting warm from extended cranking--poor battery to frame connection. Still no fix until replacing coil. Previously installed new coil when problem first occurred. Went back to the original coil, bumped the starter, car started right up . This ordeal was very frustrating. Hope this info may help someone else with similar problem.
