Idle drop by 500 rpm?

Well, just finished dinner. Went back out, fired it up, gave it the smallest pedal w/ foot brake, and it stayed running in gear. Probably just need to close the secondaries back up, and leave it the heck alone! I'm not a professional carburetor tuner I may be trying to get this thing dialed in " too much"... lol. I know I had less problems when I didn't mess with it! Thanks George!
Sounds to me like you are closer now, but have at it. I sure wish we were local. I would figure it out for you.
