Aero Nut, if I loose rpm with this mixture when I remove the glow power, would I benefit by then adding the 20/10 car fuel to the glow portion of the mixture to bring my nitro level up? This should keep the oil of the glow part of the mix at 10%, right? I'm thinking back on AV8TOR's experience with his Poulan 42 and his reports of loosing rpm with glow power off. I'll try it as you say first, since all I have to do is purchase some straight methanol and high test gas. For the gas, do you use the highest octane you can find? The highest I can get is BP93 (93 octane). Thanks for all the help.
