    Start with the high speed needle. Close it all the way douwn (turn to the right) then back it off 2 1/2 turns. After you get it running you may need to richen it up some more by opening it until you get the good ole blue smoke when accelerating.

    Regards,

    Actually I have 4 HSP vehicles and never had to adjust the low speed but I think it is the same.

    The carb opening should be set at 1mm for idle.

    if it stops when you hit the brakes , sound like your throttle linkage maybe to tight to the servo ...make sure the servo doesn't push on the throttle linkage when its in the neutral position then adjust your idle screw like the others said ..i had that problem with my Revo 3.3 when i got it ...i could not lower the idle to where i wanted because the servo was always pushing the carb open a bit ....so when i hit the brakes, the carb would close fully and kill the engine

    hope it helps a bit

    oh ya ...and make sure your throttle trim on your remote is set at ''0'' when you do that

    Sounds good to me! does anyone know the horsepower of a VX.18cxp engine? I think they give two ratings at the flywheel and the rear tires please specify. Thanks
