    I recently picked up an '01 te570... she was serviced before the guy I bought it off of let her sit for awhile. She'll start and go, no prob. I live at 6200ft, shes tricky to start cold... a lot of kicking. Once she's running she charges! I get to the top of my local trail (at least 7000ft above sea level) good luck restarting unless you point down hill put it in 3rd and pop it. The seller said it has a "new" carb, and yes it looks brand spanking new... the only prob is that it doesn't look like the carb in the workshop manual. It sounds like a carb adjustment to me but is just fiddling w/the screws gonna give enough adjustment or should I go ahead and drop the needle down a notch? Thanks in advance...

    ps: also can anybody walk me through the airbox mod that ive heard so much about

    Hi 2strokefixer,

    The air box side cover should have round circles imprinted on the inside, you need to cut them out, then glue some mesh

    on the back to stop big stuff going through the holes.

    With carbs and jetting you really need to know what you are doing it is not easy, have you done plug chops before? Can you

    set the mixture screw?

    If not, might be time to pay someone to do it properly.

    Cheers, Dave.

    It's a dellorto. As for carb adjustment I feel confidant enough to do them. I've done a few rebuilds here and there just always on 2strokes. Today she started right up, cycled the motor over a couple times w/ a handfull of soft kicks ten choke down and two mule kicks later...fired up. The choke feels like its got a spring in it that's too tight not allowing it to stay in the open position.

    I'm not going to go as deep a plug chops. As for adjusting the mixture screw, tomorrow morn I'm going to warm her up hook up the tach turn the idle screw till she's running bout 1200rpm the adjust the mixture screw a bit see where I'm at from there then let the idle screw back down... Just going to follow whats in the shop manual. Then some grinds and I are headed to bucks lake via the rubicon.

    Choke lever should flip all the way up, to almost vertical and lock. Kicking slowly and deliberately, works better than a fast mule kick..... If you stall it, hold the manual decomp lever open and kick through 10 times quickly, then start as usual and it will fire right up.

    The choke lever goes to the "almost vertical" position it just doesn't lock... It springs back as if under too much tension.
