starting by locating the 4 (four) 7/16" bolts. The 7/16" gasline to gas valve can be loosened now as well.
With the tank off, we have easy access to the flywheel.
We can now use the HARMONIC BALANCER PULLER TOOL to remove the flywheel and exposing the magneto plate, coil, and points. in the center of the photo which can be cleaned and set with the screw on the left in this photo.
NEXT, I removed the carbs two 7/16" retaining bolts. and the gasline to carb, which on this motor was an incorrect fitting. pulling back on the carb gently will now remove the carb from the engine.
which we can now inspect, and discover on this model a "junk" carb that has been
coated with sealer and an improper fitting. NOW I remove the magneto from the engine block.
starting with the flathead tension screw. and spark plug wire retainer.
