    Question Please watch and answer my question

    Hey guys I just got this new 3.3 broke in and took it out to the skate park here in town. My daughter recorded it so might be a bit shaky.
    My question is-"Is it just me or is My idle a pinch to high?"
    Here is the Vid-http://www.youtube.com/watch?v=wmwFP4nxZSw&feature

    yes, its a bit too high. I am guessing the low side is too lean....have you pinch tested to stall the engine?

    One of the hardcore nitro guys should chime in soon - stay tuned

    if you let it sit for a 8-10 seconds, will the idle go down? are you using the servo to adjust the throttle or is there play in the throttle linkage?

    yes if I let it sit it will go down a little. There is no play between the servo horn and the throttle pull, should there be??

    Idle too high.
    Idle gap too big and/or tuned too lean.

    You can’t rely on the pinch test; it will only get you in the ballpark. You should also do the pinch test immediately after a high speed run.
    You should have slight gap for throttle linkage.
    No slipper/tall gearing/power = broken parts.

    Thanks for the advice.
    I put a hair width gap in the throttle linkage. I will get it up and running tomorrow and get some high speed passes thru it and do a couple pinch tests.
