You DO have good blue consistent spark to both plugs correct?
Spitting any raw fuel out of the cold pipe?
If you can find or borrow a compression tester, that would be a good thing to confirm...
Seems to have good compression and HAS good compression are two entirely different measures. The cylinders should be between 225 and 180 psi to be considered "normal" and have a service limit of 152 psi. Anything less and it is worn out. Also, if there is more than 25 psi difference between the front and rear cylinder, the engine is beyond its service limit and requires an overhaul.
