Idle & RPM
So, when one leans out the idle mixture, would that affect the rpm everything else being the same?

It can and should have a "slight" influence in RPM's until it begins to shudder to a stop. Maybe +/- 50 RPM.

OK, not as much as I was thinking.

Many things perhaps
Greg, you may have there issues as the +/- I gave you are for a good tune as far as all else is concerned. Timing, sticky advance weights, float level, any kind of a vacuum leak and the carb internal seals all can cause adverse idle conditions which will render proper adjustment of the idle mix most difficult and almost impossible to get set.
What is the state of tune from above? Any recent work on the carb? Did you check for any vacuum leaks? Can you describe what has been done and what is currently being tried? Dave Neptune |

After you lean the idle you might also notice:
Cleaner running spark plugs. Hard starts, especially when the engine cold. If this happens check to be sure the choke is closing all the way. TRUE GRIT |

Sorry folks, seemed to have missed seeing the replies here!
I'll get back to you shortly as I hope to get the engine spring commissioned this coming weekend. And then I can report on the current settings.
