Plans to rebuild this saw in the future. Thinking about turning it into a carving saw.McCulloch Mac 130 Mini ChainsawEvolution EVOSAW180HD 7-1/4-Inch Steel. I wanted a small chainsaw that I could use in the yard and take camping and found a MAC 140 in a pawnshop. The salesguy gassed it up and ran it a few times and it worked perfectly for him so I took it home. It hasn't worked right since. I haven't been able to find a manual online so I'm kind of working in the dark.

Best thing to do is tear completly down, install new seals - clean and seal crankcase - my experance has been crankcase may have air leaks. After resealing pressure test, this will save a lot of time later. Mcculloch Mac Mini Mac Power Mac Super Pro Eager Beaver Recoil Starter Spring.

It hasn't worked right since.
I haven't been able to find a manual online so I'm kind of working in the dark. I'm not all that familiar with two-stroke engines but I've been able to get some advice.
I'm using a 25:1 fuel mixture using regular unleaded gas and Canadian Tire chainsaw oil. I measured carefully using plastic measuring cups. I'm using Canadian Tire chain oil but I've got the clutch out so that's not an issue.
Here's a picture.
It's kind of hard to see the three carburator screws. They are, from top to bottom; idle (and idle lock), lo, hi. The control on the left is the choke and I have to assume the big black button on the right is the primer. The chain oil pump (I assume) is the wire on the T-handle. I choke, pull a few times and it starts and I take the choke off. It runs for about 5 seconds, putting out grey smoke and then dies. The tabletop where I've been running it is soaked with black sludge. When I take the spark plug out, it's wet and black. I found the air filter (left side behind the pull and cleaned it). I haven't figured out how to get the thing apart to get at the fuel filter (which I suspect is the problem). The spark plug looks fine (other than being dirty). No pitting, bending or discoloration. I was gonna replace it anyway but Canadian Tire didn't stock one.
I've tried every setting of the idle screw, lo and hi that I can think of. I've had it running for as long as a minute (but not lately).
So, three questions:
1. Where is the fuel filter and how do I get at it?
2. How do I set the three carburator screws?
3. What else could be wrong?
