Another way of solving the varnish in the gas problem is to use aviation gas. Av-gas is already stablized. Use the lowest octane that will burn in your engine without knocking.

Av-gas is also available in a low lead version, which is not as much lead as gas used to have, but is better for valves than the no-lead. If you're only doing light work, the lead won't make much of a difference. The real difference will come when you load up the engine at low speeds. If you do that a lot, you can erode your valve seats without lead. Lead coats the exhaust valve, so that it does not micro-weld itself to the seat.

Marvel Mystery Oil is wierd stuff. I heard of all kinds of good and bad rumors about it, with nothing confirmed. You may try a top lube, like STP. STP is a light grease that tends to stick to upper engine parts better.
