West Bends come without puller holes. I took two hardwood 1" dowels and flattened one end of each like a giant thick screwdriver. Run a spare nut so it is flush with the end of the crank, get a friend to pry on the two giant screwdrivers and whack the nut SQUARELY with a brass hammer. Take the flywheel nut off, remove the flywheel and RUN to drill and tap two 1/4-20 holes through the flywheel 1-1/4" apart, centered on the crank hole. Get or make a puller so you don't ever have to do this again to this engine. The wooden prybars prevent scratching the rim of the flywheel. That perimeter is moving pretty fast at 10K RPM, and a flywheel explosion at that speed from stress can be a bad day for a driver. Ted
