RE: Too much oil.
Many folks are mixing their gassers at 50:1 and even less on the oil. I have run tests on my G26 just exactly like Lille-bror did on his glows and found the same results. I have gone with 32:1 in it since doing the test although it made more power at 20:1. It just pukes too much oil at 20:1 and also is more costly at that ratio. Above 32:1 it starts losing power pretty fast and anything much over 50:1, I can hear the loss in rpm's. I am glad to see this happens with the glow fuels as well as I have been pondering switching to 12%. Think I'll stay where I'm at until I do some testing on my smaller glows. (40 thru 60's)
