Hi my name Jeremy. I'm here to see if I can get some help to get my GT7 Kiehn Reed Valve motor working.I put it together fired it up.It ran normal i guess.then it went to crap.im breaking it in so all it does is run till it gets hot then fouls the plug.then it takes me forever to get it started again.the cylinder is ported for the Reed valve but they put a stock piston. I've checked and adjusted everything that you can tune. I can't figure this problem out. I've never had my first motor give me this much trouble.no mechanics near me will help me either.
