I'm backpedaling to the pilot jet.
Not sure here, but I'm believing the needle comes into play at about
1/8th to 1/4th throttle. If that's the case you are still on the low jet
until giving the cable a yank and the airflow is that of the needle and main
circuit. (Which in your case are dialed right in.) As the others mentioned,
sounds like you are rich on the idle mixture. I'm at the Lake Michigan shore
@ 630ft ASL and got the best fast idle at 1 5/8 turns, then backed off the BIG
idle screw on the side down to 1200rpm standard idle.
Never to overlook is the diaphram. A tiny leak would not be noticeable cruising
or running hard but will come into play at lower vac and airflow.
My best guess on Damocles' delete was to run a thin wire thru all of the
passages, even if you see light. Varnish can be very thin and nearly clear
but still plug off some flow. The wire will shove out anything in the way, which
can also be most any bit of flotsam from when the unit was opened up, or made
it past the gas tank fuel filter, ending up in your low circuit.
You are in good shape. This isn't major and can be tweaked out with only a few tries
or even less.
If you haven't had these things apart, grab a service manual, and youtube will walk
ya thru every step.
Mine's a black (the fastest color) '09 also and I still love the thing after seven seasons
on the thing.
Good luck and good hunting,
