[Excaliber]

COULD be a 180 out if number one lined up on the EXHAUST instead of intake stroke. The way it was firing with the Starter Fluid makes me think 'timing'. Lets assume the timing WAS set on the compression stroke and thats good to go.

20 degree's on the balancer with the 'rotor bug' pointing to number 1 makes me think your EXTREMELY advanced. I do the rotor bug thing at 5 or 10 degrees. Being to advanced would also explain the 'hard to crank' symptom. 20 degrees normally aint to much, but just using the rotor bug to line up method leaves a LOT of room for error either advanced or retarded.
