I acquired an 031 av about a year or so ago and it had not been running at the time. I ordered a new carb kit and it took some tweaking to get it up and running ok.
See what it took to get it running better:
Here is what the 031 AV started as. The overall condition wasn't too bad but there was much that could be improved upon.
Once I got it running I decided to do some work to the exhaust and intake side of things.
Intake
There isn't too much that can be done with the intake as per a few forums that I read but I figured that I'd clean it up a little and open it up some.
Now this is my first attempt at working the exhaust to try to improve flow.

Outside looking in
Now, I did get it back together and running. It runs pretty well I'd have to say. Minor gains in power but for what the saw is, I'd have to say it will be a pretty reliable backup saw or another saw to use when we are cutting up large trees.
I will get a finished picture once I am done. I still have a few things left to do such as handlebar wrap and maybe lower the squish on the cylinder by machining the base down to increase compressor. I will also post up some video as I get a chance.

I havent messed with that series of saws much so IDK if there is room for improvement or not.
