Re: 72 25hp flywheel pulling tool?
If you've got the flywheel with the starter ring, I would think about when you have to retorque the wheel. Here's what you can do:
Pick up a couple bolts that fit the starter ring, but are about 1/2" longer or so than the ones that are in it (1/4"-20 thread again). Then remove a couple nearby bolts from the starter ring and bolt a metal "handle" to it using the longer bolts. If you don't want to drill the handle for the bolts, you can just wedge it between the two.
Another idea that works on smaller engines is to make a handle that fits the puller bolt holes.
