Howdy yall, haven't stopped in for quite a spell. I thought I'd give you guys an update on my build I did 5 or so years ago. I built an 066 carcass with the stated parts in the title. I'm very very pleased still. I'm going to say it's gotten roughly 500 hours put on since the build with no issues. I finally put a new air filter in it this past weekend ( Stihl price hiked them which I didn't know) and it's running better than ever. If I recall now, these kits were just hitting the market then and quality was of a concern. Now that I'm able to attest to good parts I'm going to build another saw this winter more than likely. Anyhow guys, I'm open to hearing about anything new or revised since I built mine!
