 Re: Alcohol fuel and bicycle engines
You might be surprised but its really a pain if you do go to alcohol. If you don't take the precautions it will screw your engine up and can take it out very quick it will melt that piston to the cylinder in a heart beat if run lean or make it spit the rod out side. You might need to go to an adjustable carb they will cost almost as much as the engine kit. All the carbs I use for alcohol have an adjustable main jet. Even the simple old posa jet carbs had a mixture adjustment on the main. It even has a fixed main under the mixture screw that you had to drill out to 0.048 to 0.062 range fine tuning was with the mixture screw under power. I tried it on the stand one time and I had to build a new engine over revved it with out trying. Spit the rod right outside the block. The outlaw engine is using a tilliston carb drilled for alcohol and has adjustment for low and high speed . You can run alcohol but be ready to burn one up they are not forgiving,lot more to take care of the flushing will wear you out. |
