That is a good looking Eindecker. I just started playing with a "professionally" converted Ryobi 31cc I bought. I got it to pop once by hand but it wouldn't run until I used a electric starter which after trying my Hobbico 180 torque master I had to switch to my 5A drill with a attachment I made to use the starting cone. The 180 torque master starts my 23cc ST 2 stroke glow fine (actually that is usually just a back flip to get started) but on the ryobi it gets one revolution and then never makes it past rev 2. I know I have read that with these conversions sometimes they have to be spun fast to make spark. Did you find that to be true of your Poulan engines? It also seems like the ryobi doesn't prime well by just covering the exhaust. Even if you use uncap the one outlet and use the bubble pump to prime and get fuel to the carb it doesn't seem to pump into the engine without it spinning with the starter. So it looks like I'll be in the market for a gear reduced starter.
