You are talking about the large drill hole on the flywheel is drilled all the way through. Don't believe that is correct by the chart on #21. Chart says it's like a 1/2 inch hole and a little more than 3/4 inch deep, not all the way through. So yeah a definite concern.

Lets get a run down on the rest of the engine, step by step and make sure things are good there before we go back to the flywheel. You may need to put a clutch in it some time and that's a good time to do the flywheel then.
