Someone may have cranked the screw in too tight at one point and messed up the inner wall of the venturi, which is keeping the throttle plate from re-seating. I loosen the screws on the throttle plate and adjust the plate while looking up from the base to get the tightest fit possible when I rebuild a carb (don't forget to re-tighten them!) That's how I get the Carter BBDs to drop idle to the point the motor barely even spins at idle. I have the 1 bbl intake and Carter? carb complete from the '85 2.5L AMC/Jeep Cherokee I converted to Renix TBI (runs real nice now. I think it failed the emission test before because the timing chain was 2 notches off! Feels more like a 4.0 under the hood now) That's on the for sale pile now. Last time it was run was in the fall of last year.

Or upgrade? Or rebuilder? Message-ID: <AANLkTilt11YsAIQhE4BJ63suDBMVSODqgInratfnfoLH@xxxxxxxxxxxxxx> Content-Type: text/plain; charset=UTF-8 I rebuilt the 1909 I have about a year ago. It cleaned up nice. I replaced gaskets and jet - but the idle set screw (or whatever big 'ol screw it has) seemed stripped out a bit. Turning it in did not do much. The carb works, and I got some good miles out of it. But I could not get the idle slow enough. It worked fine for grocery trips and heading out on the highway, though. I'm thinking if I pick up a rebuildable and send it in to be professionally done - hopefully it will address that issue. And I will keep mine on the car while the rebuildable is out getting done - just in case the subdivision covenant folks come knocking on my door (want to make sure the car will start - don't expect any hassles, but gotta make sure). I had the tank cleaned about two and a half years ago. Replaced fuel lines. Replaced the fuel pump a while back - and the filter is pretty fresh. However - I wanted to see if my fuel gauge was accurate after replacing the fuel sending unit - so I ran it down to less than an eigth of a tank. I definately could have picked some junk up. _________________________________________________________________ The New Busy is not the too busy.
