Default Noob with a problem

I bought a used Gary Fisher mountain bike with a Skyhawk motor and a broken chain for $100

The motor supposedly ran and I figured for the price I at least had a good bike and a bucket full or kit parts

The problem I'm am having is that the motor seems to have compression only half the time

When I first tried to start it I would pedal and sometimes I would get good compression and it sounded like it would start, and sometimes it had nothing

I put it on a stand and pedaled by hand with the clutch engaged
Half a sprocket worth of turning had compression and half did not

Any ideas, or am I looking at the wrong thing
