If you have a consistent and bright spark, a good measured delivery of fuel, verified even compression on all four cylinders but it will run but not past a certain speed, have you considered that the difficulty in cranking it with the handle might be due to a fracture in the crankshaft? Is there an "unusual" noise when running?
I'm probably talking out of my fundament here but if your reported symptoms are accurate and you've tried all the various suggestions we all seem to be at a loss... the engine seems to be fighting itself. Is it easy to turn over on the handle without the plugs in?
I'm still thinking distributor personally, having experienced random erratic running with a very tired one, the replacement transformed the engine. I would never trust a condenser or points set replacement if it didn't come out of a sealed packet.
