    Ummm...... Temp fix, but could you slightly bend the throttle blade that is low so that it covers the hole same as the high blade????? Not sure, man. I sure as heck am not a carb expert. Hopefully someone who is is up by now.......

    loosen the screws that holds the blades in place and tap on each one until you get then even, tighten screws. they should move around. i know im no dave or tech but this should help.

    Be sure to back your idle speed screw off so the plates will close completely when you're setting them, and tighten the plate screws with the throttle completely closed. This assures proper alignment.

    if its not a vac. leak then it sounds like its still in that base plate. sounds like the linkge might be holding the butterflys open a little. have you taken the linkage off of the carb., from the accl. to see if it would idle down that away? . how do you get it to idle down, by holding it closed with your hand? just some thoughts.

    Bent throttle shaft? Some fast gouges and no throttle stop or a little outa whack and twistomatic.or just months and months of gettin floored and its got a little twist to it ?Did u use the same butterfly shaft or does that come new in a base plate?
    Its gunna take longer than u thought and its gunna cost more too(plan ahead!)

    also going to drain all the coolant and put in a 160* or 180* degree thermostat havent decided yet. have the 160* probably going to use it. changed the oil smell like gas was dirty as heck. carb was running rich for a while thats probably why.........scooter

    recheck your timming on the engine then back off the timming about 4 degrees and see if that helps. too much will do that to the idle and\or there may be something broke or stuck in the dist

    Hey Dave,

    Good tip, but check the date. This post is from 3.5 years ago. I think he has it solved by now

    Of course, that's just my opinion, I could be wrong!
