No bushings and the shaft seems to fit well. I have been reading my service manual and may have found a small problem but I can't tell until I take the carb off again. The throttle blade is supposed to have the small c facing the idle port, I'm not sure if I have it that way. What would the affect be if was 180º out?
So I put the throttle blade on the right way, cleaned the plugs and fixed a few dribbley lines. While I was at it I decided to separate the manifolds. When I did I found a spot about an inch long on the engine side of the mating surface that was a little sooty, apparently there had been some exhaust getting out. I board sanded it out, put some high temp gasket stuff on it and reassembled it, and checked all the settings again. Started it up and played with it, no change at all. I think I'm going to have to move it out for now, I have some real work to do I have a CJ2a to paint and lots of yard work to catch up on. I think my next step will be to send scout pilot the carb some time in the future and have you go through it so I can at least eliminate it from the equation. I have a not so great video I'm going to try and post that shows me playing with the choke, adjusting the idle mixture screw and spraying starting fluid everywhere.
Another update, I took off the exhaust and intake manifolds and replaced them with another set I have, real ugly but serviceable. To make a long story short no change at all, I'm running out of ideas. You should be able to see my lousy video now, sound isn't that great and it's shaky but you can see it.
You, my friend, have a vacuum leak. Vacuum gauge says so. Closed choke says so. High RPM (no wonder you got little or no response when you sprayed it) says so. One man’s “seems to fit well” is another man’s way beyond .005” allowable gap.
I really had no base line to go by, this thing didn't run when I got it. I had nothing I could say this is good so it must be that, the guy I bought it from didn't even speak English his daughter in law was translator. Next time I will know better.
