Great Planes Switch Harness
 

I recieved a H9 Cub that is using a Fuji 31. It had a GP switch harness installed. The problem is the person messed up the push rod. It is metal and its not the right size. My question is, as long as the kill switch outside the plane works, would not just closing the carb kill the engine, and do I need to worry about getting the inside switch correctly working? Thanks
