Caleb's right on the MMO. I think the biggest benefit is it's ability to loosen up carbon and varnish deposits on the valves and rings. It can often prevent or free up sticky valves in the Atomic 4, and can boost compression by freeing up the rings. I would think it would have the same benefits in the Palmer. It burns quite well (albeit smoky).
He's also right on avoiding ethanol (in the gas, not necessarily in the skipper). It does clean varnish out of the fuel system, but is awful at separating out of phase and getting water into the fuel. Loosening up the varnish can lead to lots of carb and filter plugging until the system gets cleaned out.
