<div style="margin: 0in 0in 0pt"><span style="font-size: 9pt">hello,
i am breaking in my RCG 26 CC, a friend of mine changed the high/ low valves positions, but am confused about the original setup
the max RPM 7200 with 18x8 wood prop, and the most strange thing i'm facing that the engine reaches the max RPM before the throttle reaches to its end point,

any idea how canget the optimum setup of this engine??] to make it idle on 1400 and reach the max RPM</span></div>
