A: Make sure the set screw on the choke side is backed off. Try twisting the body of the carb. If you can, then it's time to come off and tighten the screws that go up from the bottom. Also recenter the throttle plate by loosening the screws slightly and look up from the bottom towards a light so you can move them around and also make sure it opens/closes easily and all the way. You may also have to open the idle stepper up and center/close it to get the best resulting idle. This is all assuming you have no intake manifold leak and the PCV hose isn't rotted out or the valve jammed open. Make sure the power brake booster isn't shot and causing a vacuum leak as well. The hoses from the intake for the cruise and heater controls could be split someplace. I'm getting ready to pull the one on my '82 Spirit off and sell (along with the 2 bbl intake. I have several of those '80s intakes now with exhaust manifolds too) From: Brien Tourville <hh7x@xxxxxxxxxxx> Subject: [Amc-list] BBD carb 'Adjustment' To: amc-list@xxxxxxxxxxxx Message-ID: <467E0766.2040501@xxxxxxxxxxx> Content-Type: text/plain; charset="iso-8859-1" From: Marty Bricker <mbrickerusn@xxxxxxxxx> Subject: [Amc-list] Carb adjustment I had some problems with my duaghters 83 Spirit with 258 and BBD carb. I did an ignition/Nutter bypass and, after setting the timing to 8 BTDC, I can't get the idles to below 900-950. All of the adjustment screws are out (ie, not touching anything) but it won't adjust any lower. Car starts and runs great, just idles a bit high. Is there an adjustment I'm missing somewhere? Thanks.
