    What would happen if you had another cable going to the TB - and could keep it open?? I don't think the E throttle has a push pull - I don't know though. I assume the other timing would continue to pull back..

    I use to do that on a governed Briggs motor. Of course it did blow up. :-O

    Cheers.

    Just to clarify..... this is 16.048 PSI or so psi @ 9000 rpm on stock S/C wheel.

    with a 13/16 prop 9000
