Hi Dan,

I’ve tried that trick before and it is helpful, the only difference is I didn’t use a copper pipe on the gearcase, but I have leftover parts from other motors I can use to make it a ‘truer’ test. I usually just use a normal battery drill and make sure the teeth on the drill are lined up with the driveshaft splines to avoid mucking those up. It is very helpful…just had to learn to make sure that the gearbox isn’t in gear…because the first time the thing ran away from me and wound up 4 feet down in my oily barrel!!

Plenty of cussing and a greasy arm fetching that thing from the bottom left me with a good learning lesson!!!!!!
