to my understanding the oil in the glow fuel is all that is needed. that is if your engine has needle bearings at the big & little end of the connecting rod. I think everyone is using gas to help keep the cost of the fuel down and no other mods are needed. I am not concerned with keeping fuel cost down, i like the idea of sheding the weight of the ignition system plus some added power from the alky & nitro. My motor will only be ran for a short time, so, maybe i need to run straight glow fuel for maximum preformance. Now i need a carb set up for straight glow fuel. anyone know how to set a carb up for this? Frank
