    Where is the Idle screw on a 2003 Blaster , I found the Idle Mixture Screw but can't find the Idle adjustment screw , it seems like there are threads for one but it is not drilled all the way through , do you adjust it with the throttle cable? thanks.

    Top of your carb cap, there's a thing attached to it, prob the size of the carb itself.
    It's part of the TORS system, there's an idle know right on top of it.

    unless someone took the tors unit off and didnt put a idle screw in

    other wise yeah take the seat off and move that rubber flap up by the tank and the knob should be right there.

    That explains a lot. I wish I had known that a few weeks ago when I got my new Blaster without a TORS.

    You cant just turn the screw willy-nilly...

    Turn it all the way in (clockwise) then back it out 2 turns.

    it should be somewhat close. clockwise makes it idle higher, counter lower. Once you get an idle, only adjust in 1/8 turns, wait 8-12 seconds before turning more

    It may pay to start a new thread if the following does not help.

    Idle adjusting.

    Set float level.

    Start with air screw 1.5 turns out.

    Set idle screw so that it has some sort of idle. With TORS it is the big screw under seat on top of unit. With no TORS is is the brass screw midway down carb body.

    Warm up motor and then set idle screw for a faster idle, 2000rpm+

    Adjust air screw either way to get the fastest idle.

    Adjust air screw a little at a time leaving 10 secs or so until the motor responds.

    Re adjust idle screw for desired idle .

    Can be adjusted easily with the seat off! You'll need a flat head.
