RE: Where do I begin?
The Cool Power should work fine. I've used it in similar two stroke engines with no issues. The Wildcat Premium Extra linked by Phoenix is also a very good choice. If there is any way to get your fuel locally I recommend doing that. The HazMat fee to ship fuel is something like $25 so it really drives the price up.
I have used
Cool Power, Omega, Wildcat 2&4 cycle, Wildcat Heli Mix, Powermaster, Ritch's Brew, Magnum, and probably others. They all work well.
