A points flywheel will not run with a no points magneto coil..,If you look at both flywheels you will see that the keyway is in a different location relative to the placement of the magnets...
If you want to run the engine with no points, I can send you a new G38 coil that works with the original flywheel, better than the original setup...$40.00 shipped, bolt it on and run..This will NOT fix the fuel problem....
There is no gasket between the bottom and the top of the case, just sealer..
The crank seals are on both ends of the crank, outboard of the bearings...Check out the parts drawing on the B&B website, page 11, part #100027, one on each end....
