This Poulan thing just hit me, I stopped by my favorite Auto Parts and other things store today for some metric cap screws and the operator ask me if I would be interested in a Poulan Chain saw for parts. "SURE" Well, when we got in the backroom, he unloaded three Poulan Pro saws on me just to get rid of them. A 35, 42 and a 45. The 35 and 42 had an exploded or broken spacer washer in the centrifical clutch, and the 45 had an out of round centrifical clutch housing. There are some other minor problems, but all very fixable. I had the 35 and the 45 running in about an hour, but need some additional work on the 42. It appears to me that these may be a very adapatable conversion engine. What can anyone tell me about them. All are near new. I am a Ryobi nut, but???? Flathead 4
