    RCS 140 Problems starting & top end


    I have the RCS 140 which I bought because of a review done by Ray at Kangke and it has been problems from day one. I have had it and the plane (Monocoupe) for several years, never even flew the plane, just got fed up and put it aside. I have sent the engine back TWICE and they say nothing is wrong and turns 7800 rpm. Unless you use an electric starter, it WILL NOT start cold or hot. Obviously I am still using FRESH 40:1 mixture and only can get 7,000 rpm on a 16x8. I probably have over a gallon of fuel through it try different things.

    Does anybody have any suggestions other than using it for a paper weight? I have a perfect rating on RCU and will not even sell it.

    I am beyond being upset with this engine. I have almost as much in shipping as the engine by the time you add up the insurance and other shipping charges.

    Thank you,

    When was the last time you sent it in for service? What is your last name?
