Thank you ahicks for respecting my opinion. It’s not my opinion. It’s Futaba’s. I too read the DLE manual for their 20cc engine and would you believe it, they have the same opinion. Keep the RC and ignition system separated and don’t use metallic pushrods. It sounds like the OP should get in touch with the manufacturer of his RC and see what they say. Dan.
