At that much open, there would be practically no flow. And if you had idle instability as you said, hung idle, that also points to idle too lean. In any case, with warm summer weather, you should need no choke to start from cold. Might be a tad lean for the first min or two, but run fine. Cant hurt to try another half open I say.
The RS carbs have the enrichener/choke as the BS34's, so cold weather cold-starts are done without touching the throttle.
I have not figured out the warm weather cold-start method for the RS carbs yet...rotate the throttle partway and hold it, or just enough to get the pump to squirt a little fuel in and let off, before hitting the start button?
Ran with Pilot Screws about 1 turn out for a short while today. The motor sounded like a person trying to talk while gargling with old apple cider vinegar. So back to 3/8, where it seems good again. But now the needle clips are back in slot #3
Still not sure the best way to start it...tried pumping the throttle a couple times, without pulling the choke knob out.
Crank, crank, crank, d-d-d-d-d-d, crank, d-d-d-d...
After that, it didn't even want to start next with the knob pulled out, but did fire after a brief rest and couple more tries.
