Funny, I’ve been using my 3.7 (one of my first carb jobs) a lot lately. I have thinned out a lot of saws. But this is one of a few that stays put. I hadn’t used it in a few years. Fired right up but pi$$ed fuel out from the top. The lines I ran 10 years ago shrunk so I ran a new one and re tuned. Had a good 20” bar and mostly sharp loop of rsc on it. Ran right thru some bar deep frozen red oak. All stock but a 4000 intake and one of marks 5200 style mufflers160 psi. I’ve had 3800 and 3400 saws and these thin ring saws are noticeably stronger. When I had my 4000s I couldn’t tell the difference and those were tight saws.
Found a cool coke bottle from
The 80s and a nice blue quart Ball jar.
