I help out a neighbor widow with her farm and yesterday she asked if I was interested in any of the old junk in the barn and of course I said yes. Right off I spot an old red beast in the corner and went to rescue it from the junk pile. Well it is a Mall OMG with a 30 some inch bar and looks to be intact. It has spark, it is missing the stop switch and turns over with some effort. No scoring of the piston is evident thrhrough the muffler port. The spark plug was new looking and it looks like the piston nudged the ground electrode tight to the center electrode, no damage to the piston could be seen through the plug hole. Some questions I have are:
1. What is the correct plug
2.Is this saw direct drive or is there a clutch, and if it is direct drive what would cause the sprocket to not turn when pulling over.
3.Any links to manuals and parts lists.
4. The air filter looks to be some type of permanent type and how to clean it.
5. The label says 1/2 pint of oil to each gallon of gasoline, do you mall saw owners run 16:1?
6There are two knobs on the side one looks to be a gas shut off the other one has numbers on it,what does it do?
7. any carb kits available?
Thanks in advance,Ray.
