Thanks for your reply. When I first installed the distributor, it turned just fine, but the round piece that is surrounded by the O-ring is sitting on top of the engine. After it runs a while, the distributor seems to have been pulled down so that the round part that is surrounded by the O-ring is flush with the engine. Then I did loosen the securing clamp and was unable to turn the distributor to set the timing. It was extremely tight and I couldn't move it at all. I used a bar to pry it so that I could turn it, and then I just pulled it out.
Then I seated it back down in there again. It could turn really easily until I ran the engine for several minutes, then was tight again.
The engine did seem to run really well, except for being unable to accurately set the timing.
