Every once in a while my 6v92 ta. starts rough maybe once in 50 startups, I shut it off and restart and it is fine,it seems that it is more likely to do it when the fuel tank is low around 1/3 tank if that makes any sense, it didn't do it all summer now twice in 2 days! anybody have this problem? it starts very easy hot or cold, thanks for any suggestions.

It does run rough if there is air in the fuel line. Then smooths out once the air bubbles are passed. You might have a little leak in the fuel lines or filters somewhere.

Dribbling injectors will cause that also the injector leaks down then when running fills back with fuel, but most of the time that is noticeable by more smoke on start-up

good luck
