Alright, so I recently picked up a very clean and sweet Jonsered 670 super. After I purchased it, I used it for roughly 5 minutes removing the top of a stump. The next morning I found the chain frozen...the chain brake somehow locked up on the drum, even though the arm was in the off position. So...I got a used (good) band and it fit. Well yesterday I was using it and after 2 minutes I see smoke coming from the clutch cover!! For some reason the brake band is locking up. The clearence between the band and the drum is very close, but fine when the saw is cold. I put a zip tie on the arm to pull it back towards the handle, and the saw ran fine all day. I took the clutch cover/arm assembly apart and found nothing wrong. So the only thing I can think of is the drum is out of round and heating up the band? I'm almost ready to pull the trigger on buying the husky cover off of Baileys web site, but...I have a full wrap, and I think it might not fit.
Any thoughts or ideas??
