The octane rating on the pump is hardly accurate. Industry calls it "Average", it is basically the detonation point that a test group of engines detonate at. Aviation and race fuel are measured in true octane or the ability of a fuel not to ignite prematurely. For the 2 stroke engines(most) I concur that regular fuel is fine. Compression is not anywhere near high enough unless you have sharp edges in the combustion chamber(there is another thread on this somewhere)
Enough outta me.
