    It can be accomplished with jet and rod changes , and with the you shouldn't do it adjustment to the APT .

    this is completely stock, so it has the stock needles, etc. i just need to know how to get it from running so rich, it just needs to be a quick fix for now, until the guy buys a new carb, just really embarrassing to drive right now

    Bone stock , start out with a simple tune up first , plugs , cap/rotor , etc . An oil change too . The idle mixture has nothing to do with it running past idle , so just set that to idle best . And with the timing set to stock , see what it does and post up :grin:

    The blue smoke ( oil ) isn't going away until the motor/heads get rebuilt .
