Dumbo The Flying Elephant

[Larry Hill]

In trying to make more power I know we need to raise the RPM level. To me that means paying attention to fits. Well I found this one by accident. The gears that go on the crank that drives the camshaft are black in color and have an ID that has been bored. Two out of the three gears still had portions of the ID still black in color and fit looser on the crank. I do have one that cleaned up on the ID and is a good sliding fit on the crankshaft. I don't know if that could be a potential problem at 150 Hertz, but just trying to keep everything straight and round.
