  • Re: Carb Sync above 3500 RPM?

    by » 3 years ago


    Just my .02 cents,

    It's not just for the cross over tube. That's down in the idle rpm circuit. I want the carb cables and throttle levers to stay in sync as I procede up into the higher rpms. If I sync at only 2500 rpm the carbs go out of sync as we go on into higher rpms. Usually if I sync in that 3300-3500 rpm range they tend to stay synced as I apply throttle into the higher rpms. So syncing at low idle rpms is important and syncing at higher rpms is important.  

     

    The one thing I wouldn't do is what one organization does. They back the idle stop screws completely out of the picture and only sync at 2500 and thats all. I've tried this just as an experiment and they are never synced at one end or the other.
