There is absolutely no fuel in this thing and I have the compression problem. I've narrowed it down past all the fuel problems and I am stuck on this compression thing.
Don't get me wrong, thanks for the replies but it IS NOT A FUEL PROBLEM.

Yes I have made sure it has a washer under it.

As soon as I get the plug in one thread the problem starts. It is hard to turn over at that point. If I turn it down all the way, I really have a tough go.

THERE IS NOTHING WRONG WITH THE STARTER. I have tried two starters and two batteries as stated above, I can start other engines.

Thanks again for the replies. If they don't help now I'm sure they will in the future.
