On another note. It turns out the crankshafts are not completely compatible. For the older engine with the points coil, they machined a flat onto the crankshaft. This flat is to allow a pin to rise and fall, allowing the points to contact. This flat is not on the newer crankshaft that uses the magnatron. I would have to ditch the old coil and fit a magnetron for it to work. Otherwise, of course, the points would always remain open and never produce a spark.






I have a new PTO shaft key. Should I get the clutch half that has the set screws. One screw would pin the key to the PTO (I could even notch the key to prevent movement) and then the other is at 90 degrees. The key shouldn't be able to move then. In this position (past the notch) it is still a tight fit.
