The 1905 AVS2 should be a mechanical choke? Do you have a cable controlling it?
Yes, I do have a cable on it. And use the choke frequently. I make sure I get the cable set properly (no filter housing on at that time) when I have to pull the top of the carb off to swap main jets. But, putting the filter housing back on top after getting the cable back properly, maybe I didn't get the housing on right last time in regards to the choke.
