Wondering if someone can help? I just rebuilt my weber 40 ida's. Soaked it all in parts cleaner, carb cleaner and compressed air. All passages seemed to be cleared, reassembled it. I'm trying to install and balance them. The problem is that the syncronizer measuring the left carb bank is reading between 6-7 at 1000 rpm. The right carb bank is reading 3.5 - 4 (this is with the linkage detached and the idle screws turned in 1/2 turn on each bank). I can only get the right bank to register the same as the left bank if I turn the idle adjustment screw in about 4 turns!!!
My initial settings are:
idle air correction 1/8 turn out
idle mixture screws 2 turns out
anyone know the reason why this is happening?
any help appreciated,
thanks,
Keith
