Hey I am buying a blown 13b for 50 bucks to re-build it. I want to re-build the motor to be a simple as possible. It will be used in a shifter style Franken Kart, I am not familiar with rotaries so I am wondering how I can make this user friendly. Such as: a carb instead of fuel injection, simple cooling, NA, ect. Let me know what you guys think. I have lots of time as I am actually doing this for a fair next year.
