RE: What engine on a Power Mac 310?
Took it apart this evening at work. It has a really large Zama carb. A split crankcase. The carb is mounted on the front to a roundish rubber type intake manifold. The carb does not have a pump hole but seemed to have a hose that ran from the manifold to the carb. It was missing. might be why the saw wouldn't run. The cylinder head and the upper crankcase are one casting. When I pulled the crankcase apart, I found that the piston and cylinder look almost brand new. The piston has two rings on it but they are not pinned. The muffler was tiny. The only thing that would need to be cut off is the part where the chain bar and the chain oiler mounts. There was also a hole from the oiler into the crankcase. I would assume that this hole would need to be closed off somehow.
This looks like it would make a really good conversion engine. I left it a work to show to my buddies tommorrow. Will bring it home then and take some pics. I am thinking this might be good for a GP Tiger Moth that I might acquire or it might be a better engine for my Dynaflite SE5 than the Ryobi 31cc that I have already converted. If powerful enough it might even work on a light narrow cowl warbird. So far I am pretty excited about this one. Any suggestions on how to proceed on the conversion?
