Great info Scerb, this gave me the confidence to give the rebuild a try, I've torn it apart and cleaned it, starting reassembly today.

One question though, my truck was occasionally dieseling, so I figured the idle cut solenoid was bad. Got a new one, replaced it and now the truck would not idle. Just died every time I let off the accelerator. I noticed the old solenoid did not have that little rubber o-ring on the tip of it, put the old solenoid back in, and still wouldn't idle. So I disconnected the solenoid and STILL would not idle. It was time for a rebuild anyway, so I tore the whole thing apart thinking maybe something was jammed up in the hole where the solenoid goes, but nothing in there. Any thoughts?

Again, great carb info, thanks!
