The "Fire it up without the gib key installed" method probably won't be found in the repair manual. However, the torque of the crankshaft accompanied by the many orders of harmonics will probably loosen even the tightest wheel. Cheap insurance aqainst a runaway flywheel would be a hoseclamp installed on the crankshaft. Two clamps, better still. Might not want to wear flip-flops for this procedure.

The "Indian Loctite" appears to be red rosin made from pine trees. Can anyone confirm this? If this is the case a penetrant may be helpful when trying to remove the keys. A couple of applications the day before would probably do the trick. Turpentine would be solvent, as it also comes from pines. However, any light hydrocarbon would probably suffice. If anyone knows for sure, do tell.

I forgot to give credit where due. This puller was designed and built by gpkull. It worked well on both his 24/2 as well as our fathers 12/1. You'll see an electric impact gun in one or more of the photos. This is shown as an example of what not to use. Never use an impact on a puller. Not only does it typically wipe out the threads in short order, it creates the potential for the project to turn painfull and colorful in about a split seconds time.  Slow and steady is always the rule when using puller. That being said, build and use this, or any puller for that matter, with care. Cheers........

Thing of beauty. Over engineered tools to work on underengineered machines. My brother built a key puller from some scrap material that could be duplicated for no more than the cost of a few nuts, bolts and beads of weld. I'll try to get the pics posted in the next couple of days. Cheers
