    With the gravity feed fuel tank;  do you think the carburetor needle/seat might be seeping ever so slowly that over time it floods the engine?  Does the fuel shut-off valve work 100% ….and are you using it?

    If you think this could be the issue….you could tilt the engine up just a bit…..which would allow the carb to drip out the throat into the silencer as opposed to running inside the engine.  Maybe even remove the silencer so it would be easier to see the dripping…..

    The solution would be to re-visit the functionality of the needle/seat.
