Fired my 3700 up for the first time. I've had this saw for almost a year, got it real cheap, was a basket case and missing parts galore. I would like to thank all those who helped with parts, or who offered parts. I must say Sears Parts Direct seems to have quite a bit of old Poulan parts hanging around the warehouses, and their resonable pricing and quick shipping too.
Anyway I needed just the clutch plate washer and sprocket washer, they had em and I got em today. I also got a brand new bucking spike from Randy on ebay. I also used an old carb gasket that seemed plyable enough to work. Keep in mind I did even know anything about the carb, sooo I gassed her, got her to idle, but, no high speed, part throttle OK, but wide open she'll stall. So I figured I need a kit, but I pulled the carb appart anyway. I seen what the problem was the main check valve screen was clogged solid, I happend to have a few extra, so I sprayed the carb with cleaner and blew it all out, reassembled, headed out to see again. It was evident right from the first pop, once I got it adjusted right she screams now. I also am using my 4000 muffler with a drilled diffuser on this saw because I did a 4200 style mod to another for the 4000, so she sounds sick. Just gotta pick up a bar and chain, this is running an old 16" bar and stock Poulan P72S chain. Thanks to all, very excited right now, have almost the entire line of mid weight Poulans, except for the 3800.
