Hi rsjr! My friend has a 340 model of that chain saw which fits your description perfectly but his is a 35 cc, we converted to airplane usage and believe me it has a lotta power try to convert it you will like the results, if I can get a hold of a digital camera I will post some pictures so you can see how the conversion was done, right now we are waiting for the bearings that we ordered because the engine had some play on the ones it came with, but believe me it has POWER. In case you decide not to convert it let me know if you will sell it I would buy it from you if you want to get rid of it?
