First time I've worked with a Schnacke starter. The flywheel nut has teeth and the starter pulley has matching teeth that extend and engage theJust flywheel nut when you pull the rope. The trick was to add a spacer between the flywheel and nut so the axle threads were below the teeth. The teeth on the original starter were chewed up a little so I believe it was not set up correctly. Luckily, the part on the second saw was good so I changed it over but found it extended in too far and was hitting the flywheel nut teeth. I then had to make a spacer to move the starter outward and keep the teeth clear of the flywheel nut until the rope is pulled. All came out well and I have spark now. I went ahead and put the tank and rear cone on for pics. I still need to double check everything before adding fuel and attempting to start and I don't know what to expect with the pressurized fuel tank. Still looking for an operator's manual. Here are pics.
Edit - just realized I didn't post any "before" pics. Here they are. I didn't know if the red stripes were factory or not but thought they looked cool, so I added them.
