What got me in this mess was that my truck was running perfect except my idle would hang up so id have to flick the throttle and get it down and despite being told the carb was just rebuilt, it had leaks and gumminess everywhere. During the rebuild I found the shaft linkage had play and spun a tad before opening the plate. Basically the lever had play before the shaft would spin. I didn't want to hammer the end bushing and wasn't comfortable brazing it myself. I only have a mig plus I'm a novice welder at best. I rebuilt it and set the linkage where I thought it SHOULD be and I put a thin film of jb weld on it. Worked like a charm...except I did it before putting it back on the truck and now I believe the throttle plate is closed so far that it won't idle. There not being an idle stop set screw makes this tricky. I'm going to mess with the throttle cable and see if I can get it to work and do a deep vacuum leak assessment. Of course after the fact I read reports of others drilling and tapping the end shaft which will likely be on the table if I can grind off this jb weld and can't find a reasonably priced carb or shaft.
