The rubber gas primer bulb became brittle with age and discitigated & ignition switch was defective so the engine wouldn't start.

With the help for your great website I was able to look at the detail drawing and figure how the machine comes apart. Especially when I had to
rewind the recoil starter rope.

Snow blower would not shut off with key.

Just removed 2 screws to bottom plate. I unplugged wires to switch. Pushed in on both sides of switch and pushed up out of top plate. Pushed in new switch and connected wires to it. Replaced bottom plate with 2 screws. Turned on switch. Pushed primer button and put on choke. Pushed electric start button and it fired right up. Let it run for a minute and turned key off and it stopped running. Problem solved.
