Why do you mix fuels? The EG motors I have seen run pretty good on stock jetting. Who ever modified it should have an idea. I would say, keep checking your sparkplug. No one should know your jetting better than you.

i mix the fuels to strech out the race fuel,i mean gas prices these days u can afford it,its cheaper and u still get the needed octane by doing a 50/50 mix

It is out of the can or ground? How much per gallon? If you go and modify an engine, and make it high compression. Then why kill the throttle response? If you ever feel snaky, try some Firepower 537 with some boost. Ether responds a lot better than alcohol. The firepower comes as a raw basic race fuel, the boost brings it beyond anything else I have ever tried. Cheap racing, I would go with out food first! Been there done that. http://www.precisionautoresearch.com/page2.html
