Starting to run out of ideas here, just manually tested the vacuum choke pull off and it works.

i had the return spring problem a lot on my weber 34. the springs just wouldn't pull the accelerator arm back enough every time i let off the gas. sometimes that would and sometimes it would stick open at 1000 rpm. it sucked. i had to put some heavy springs on and hten it was so heavy it made it hard to drive the jeep smoothly. i think it was just because my weber 34 was a crappy knock off of a weber or something. it was new when i got this jeep and it still sucked. i never had an issue like that on any other weber i have ever owned or on any of the motorcraft or holleys i have owned
I don't feel like working on anything at this time so i sold my yj.
