another no start issue!!!! (more than a little frustrated)
Sounds like the engine is too tight, if it's that hard to turn over.
Does the distributor send spark to the plugs when the engine is rotated? Or does it just buzz reguardless of where or what the position is rotor is in?
Have you check the air gap at the pickup? Is it hitting?
The bleed off of compression is normal. The ign. control box may be bad, just a thought.
