I have had my floats hang up in my ’58 35 hp. The Sierra light tan and older OMC gaskets can swell with ethanol fuel, age, or bad manufacturing. Happened to me twice. In my case the float was held open and the motor flooded out, spitting fuel from the over flow. My guess is it could happen partially closed too. Both times did it after sharp high speed turns.
No diaphragm in the single line tank. Perhaps the fuel pick up line has fallen off and when you turn it moves fuel away from pickup?
Check the link and sync of carb to timing and the fuel economizer rod just to make sure all is OK.
Tiny tach makes a good induction tach that wraps around. Plug wire
