Well, I hate to drudge up old threads, but I owe you guys a thank you.
This exact issue showed up on my 2139t after some porting.
I know it is hard to see the good when a porter/chainsaw guy is shown to be dishonest or has undesirable work ethics but I want to take a moment to point out what is right with you guys. I just saved two years of troubleshooting by adjusting my carb with a drill bit. I remember a fix that tree monkey shared for 199 carbs that helped me as well. Masterminds old build threads on AS were the reason I tore into my first saw, a 2159. Srcarr52 helped me build a popup for my 2139t—-something that would have been frowned upon in some circles. Drf256 brought me from the other forum due to a JB weld discussion and the learning hasn’t stopped since.
The information you all share is truly awesome and much appreciated by us non-pro hacks.
Thanks for being a great group of guys.
