Got it figured out. I was using an aftermarket Shindy carb kit and installed the Shindy slide needle and left the OEM needle jet in the carb body. This caused the high idle as the Shindy needle has more of a taper which was a looser fit in the jet.
Next, I changed the slide needle back to OEM, but also changed the needle jet out to the Shindy jet. This was an oversize needle in the smaller jet which caused the engine to only idle under choke. It would rev and run WFO but did not idle. This is when I thought to match the needle to the jet and used both Shindy parts. Fourth notch from the bottem caused it to rev as in first paragraph; second notch from bottom had it idleing and runnning WFO. Hope this helps some else.
I just read this thread for the first time. You did a good job of troubleshooting!
Now I know why I never use generic carb kits. If you would have bought a new factory needle and seat and a gasket set, you probably would have saved some heartache, lol.
