A couple things. I am a fan of running more oil. However, many (if not all) of today's epa saws have the h jet maxed out to the limiter. If you use 40:1 or 32:1, and the h screw was already lean at 50:1, the saw will burn up. Simple. 32:1 mix is thicker than 50:1, therefore not as much gas flows through the jet. Oil lubricates. Fuel cools the piston. If you don't defeat the limiter caps, don't run more oil.
Also, I'm in Michigan. Tractor supply here stocks several saws up to a 2172, a highly regarded pro saw. The biggest husky I've seen in Lowe's was a 455 rancher. So while they may not carry as complete a lineup as an actual jred dealer, it's a way better selection than just a few home owner saws. I'm guessing it's a territorial thing. You'd have to check out your local tsc to know what they had in stock.
As for the OP, I agree with others. Your saw was meant for occasional firewood. I'd get into a 50 to 60cc saw. For one, they're built a bit better. And 2, if you're doing a 35cc job with a 50cc saw, it only stands to reason (to me at least) it'll last longer and be more trouble free along the way
