Well, I finally got some pics of the 090 I picked up last week. Threw it on the mill and did a 10" Birch log on Sunday. Cut like a hot knife through butter, but the cut was really rough compared to my 395 with 3/8 chain. I think it was just the added weight of the powerhead though because I didn't have the log secured really well to its bedding (it was late and I just wanted to see how fast it would cut), and it was wanting to rock around quite a bit. Any other ideas?
Got it for $20, so far I've put about $50 into it, have another $35 worth of various original parts coming, and will be spending another $100 or so including a new carb and handle.
If anyone has a rim drive clutch drum, clutch cover plate, 2nd dog, or choke shaft/lever (the part in the carb) please let me know as these are the only parts I can't find so far to get it fully restored. The crankcase is also cracked out where the handle mounts to it at the bottom, around the flywheel. Looks like the saw was dropped hard - the handle's bent and broken too. I'm going to try to JB Weld it, but if a crankcase came by for the right price...
