Mitty I was thinking of doing the same with a Ryobi 31cc. Just make sure you flush out the carb with some gas when flight is finished for the day. Pure methonol can effect the carb neopreme components if left to soak. also please run a good afterrun oil through the carb to coat all the bearings and prevent rust. You may consider mixing 33% methonol to 91 octane gas and elminate most of the flushing problems. good luck and keep us posted - big al
