Thank you fellas for the responses. And I concur on the carburetor shop, very generous and helpful info.
One thing I tried was to close both the jet screws at the bottom of the carburetor experimentally, to see if it made any difference at all. It didn’t. I noted the number of turns and put them back the same.
So, I did check and clean out the float bowl, the float valve, needle and seat looked clean and normal, and the level was down where it should be. Only some fine dirt in the bottom. The inline filter is functioning.
The items buoymaker mentioned for the AA-1 to check, sounds possible.
So, I’ll let you know if I have any luck!
