Took it for a ride, idles a lot better. seems to really like 1400rpm so thats generally where i leave it. Starts easier. Still a bit of stumble, but it seems alot better than it was. Seems like they dont like agressive throttle where im feeling that stumble. I can roll through it. But its running great and as far as im concerned as good as it's probably gonna get till i can put a Boyer or Dyna in it. Been through the carbies a million times and did the WG coil mod. All new manifolds and box boots. Plus new coils/caps/condensers. Points are coming.
Next winter it gets some new paint and a from scratch wiring harness. Probably check my lash too while its apart.

I'm sure you checked the needle clip position on the jet needles as well?
Air jets in the Air Horn/ bellmouth clean UN-obstructed?
vacuum sync performed?
Then of course there is always the mechanical, hows the compression balance?

If carb has a side-located pilot air screw, turning the screw on carb #1 should produce a change in idle rpm. But if not, there's usually something still wrong inside the carb (likely an imperfect pilot circuit that's incapable of providing the optimal air/fuel mixture, for whatever reason).CDNTX650 wrote: ...Stumble is still there...Plugs are tan except plug one. fouled...might as well double check the ole LASH....
Would also re-examine condition of the pointed end of the adjustment screw.
That's a good idea about re-checking the valve clearances.
Good Fortune!
