"I have popped many flywheels
"I have popped many flywheels from these motors. What I would suggest is to first start out with some Liquid Wrench right on the center of the flywheel, sometimes they form rust and bond to the flywheel. Now to keep the flywheel from moving, I always use a rope in the rope sleave on the flywheel and tie it to some very sturdy part on the motor and hold the puller with my hand. If you still can not get the flywheel off, then use heat on the outside of the tapered shaft on the flywheel. You will need to use alot of heat, it will take about 3 minutes. If that still doesnt work, then you either broke/bent your flywheel or its time to break out the saw and cut until you get right next to the tapered shaft then with a cold chisel and hammer, break the flywheel off, or you can take to a small engine shop and see if they can find some other way to get it off.
