I'm sorting out a '68 GS400 convertible formerly owned by @efogs400. It wasn't taken care of by owners between he and I, but that's a bar room conversation. The car won't run without me on the gas for a minute or so, then idles @ 700, then idles at 1000-1100 after driving it. I've gone through timing, and carb mixture settings, but found the choke not hooked up. Overall, the car drives good. I'm just trying to sort out the high idle & lack of kick down, which it doesn't. The spring is in the manifold, but when I connected it the way I think it should go, the flap closes and won't return to the open position. I also think I'm missing at least a screw (!?!?!? I know ... LAYUP !?!?!?!?) and maybe something else. Here are a couple photos. Hopefully a QJ guru can tell me... I've never dug into carbs that much. Thanks, in advance, for your help.
