Tom, great that you respond so quickly, i can see the difference between the former model and the other. It does sound logical that it would have had a diaphragm carb instead of a float carb. I have a vacuum Walbro WYJ type with barrel throttle lying around that might fit. I see that I do miss the intake manifold which is attached to the membrane intake assembly. But I am still very curious about the original diaphragm carb... and oh yes Tom, my first name is Winfried

Hi guys, I am a new one in this forum. I was looking for info on this engine, and stumbled upon this topic on myoldmachine! I think this is a 22cc P7 engine. I even have the box of this machine still, and because of this I know it was the engine drill. My late father bought this engine at a dump store and took a lot of stuff off it. Everything het took off isn't here anymore... His intention was, that this 22 cc would be used for a big RC model aeroplane. In hose days there were no model engines of this size available. He made an adapter to fit a glow plug in the cylinder head, thats maybe why there is no ignition on it. Unfortunately, between the 60's and today, a lot has happened to the storage of the engine. The carburettor and ignition have been lost over the years. Everything I do have, and that is what you see on the pics, is in pretty good shape. I'm a model airplane builder myself and it seems fantastic to me to get this P7 working for a big scale model. The quality of the heavy crankshaft with counterweight (read; very good flywheel effect) and the construction of the crankcase, cylinder head etc, is in my opinion great! I see in this topic several pictures where I see the carburettor on it which was originally on it. Are there any people that can help me finding such a carb, and possibly the parts that are needed to make the ignition complete? Maybe it would be better if I put a CDI ignition on it for reliability, but that of course would detract from the originality... Thank you very much for your efforts in responding!
