Mr. Snelling messed with my brain

Well after reading the birth of a NOS 076 thread I got to thinking. I first wanted 1 of my own...but then decided since I have absolutely no use for a chainsaw, and own 2.5 of them already, why not just mess with one my current saws.

So I have 2 good Stihl 031AV saws and one donor 031av. I just pulled the jug off the dead saw that is missing way too many parts to restore and discovered that the jug looks pretty good. There is a bit of aluminum transfer and a lot of carbon, but the honing marks are still visible beneath the aluminum transfer.

There appears to be a lot of material that could that could me removed to port the spare cylinder.

Has anyone ever ported an 031? Can I get this saw close to 4HP. My better of the 2 031s is very strong as it is....but nothing says success like excess.

Honestly, I can't imagine porting a 031. But then again, I just ported a 076 . Go for it if you want to. I'm sure there are plenty of gains to be had. So long as you're aware that it won't likely ever perform like a modern saw.

The only modern saws I have run are a Stihl 200T, 029 and a Husky 455. The 200t was just amazing(for what it is intended to do). The 029 was ok but also had a dull chain. The 455 is a worldclass piece of crap compared to my 031av.

So I guess I am not looking to make a modern saw, just make my old one better. Can you give me some quick direction from my pics?

There's a member here that raced 031s for years in the 3 cube class. His were turning 19k on alky.

WOW. I wonder how long his saws lasted.

Wow. I would have never dreamed it! You're schoolin' me

Actually, he'd school all of us. I sold him a bunch of big carbs to use on his racers in the late 90's. He built some wild contraptions, like an 066 with an 056 Magnum II cylinder and piston and a tuned pipe.
