A magnetron coil (part # 397358) wil get rid of points ignition. A carb to tank gasket is a couple of bucks and the little pump diaphragm is less than two bucks. The way I remove the end of the cam is fire it up and lay the hacksaw on with a little pressure, and in less than 20 seconds it's gone. A sawzall or hacksaw with the engine not running is probably safer.
