After several direct e-mails requesting this info , I'm posting it here.
This is what I do to all my Zenoah engines-saves a lot of trouble down the road with corroded connections. The braided wire is from the outer shield of a CB radio type coaxial cable. Clean all connection points as well as the plug and socket where the coils connect and use some type of electrical anti corrosion compound. I use Penetrox but I don't think that is available in small quanities.l Sorry about pic quality . I also ground the stuffing tube to the motor mount . This has solved some hard starting and high speed miss problems as well as some radio inteference issues. Hope this helps someone.
