Tap the crank adapter with a soft mallet to help set it in place. If you have a dial indicator it would be a good time to check the run out. Install the Joeracer key in the adapter making sure that it is sitting flush and snug with no burrs folds spindles or mutilations.

Now locate the over flow hose’s from the carb. At the engine case there is a metal rod that holds them in place. Remove the screw and rod, as that’s where the starter bolts to the case. From the flywheel side slide the starter and align with the screw hole that you removed the rod from. From your pile of old case bolts find a screw about 35 mm (1.25) or so and reinstall the metal rod on top of the screw. Unless you are good at guessing the alignment of the starter in relation to th

Now is the scary part. Be very careful. Put the gasket on the engine case with the dowels. If the dowels are on the alternator, cover case remove them and put them in the engine case.
