I'm working on a Poulan 42 short shaft conversion with EI. Can you post some designs for your
prop shaft adapters? Or maybe a source to purchase one. I have a small lathe so I can make one myself. It seems that the there may be an issue with this thing rotating off of the crank shaft if there is not a positve lock, such as a key in the 1/8'" slot that is cut into the taper.
