    I was going to take it in to a local independent shop but I went to a plan 'B' instead. I ordered a jet assortment from Ebay. 60.00 bucks and be here Mon. or Tues.

    The more I think about it, the more I'm convinced it has a horribly lean condition that is due to the 'out of the box' lean jetting of the Weber. You have to figure those carbs are lean jetted to the max for over the counter sales due to EPA regs. The instructions will lead you to believe the carbs don't need to be tuned...HARDY HAR HAR... In fact that's what the instructions say- they are calibrated at the factory and there is no need to mess will the calibration. WHAT A LAUGH.

    I also read an article by Jim Inglese explaining how the thing works and the basics of tuning them. What a piece of cake. As easy as falling off a log backwards. LOL

    A dozen different idle jet sizes and I just happen to get the magic formula of correct jet sizes in mine.Yeah right...

    The idle circuit is doing the work during 80% of routine driving, and that is where the symptoms occur, during low speed operation...anything over 2000-2500 RPMS and the mains take over. This link is awesome. Keep hitting 'next' all the way to the end and you will see some of the coolest Weber set ups he has done for Cobra V-8s and so on. WOW.

    In looking back at how it is now in the out of the box lean condition...it should not take 19 full turns out of the idle mixture screw before it begins to stumble...ROFL...

    In reading that article by Jim it should only take one full turn out or else it needs to be richenend up a tad...
