Andrew,
Have you ever considered trying FAI. Granted I am not currently running any 4-strokes, but I run home made FAI fuel (80% methonal 20% castor) in .40's to .90 size engines and the loss of power is negligible. It can be bougt or made for about half the cost of 10%, between $7 and $8 a gallon here in the US.
