    I assume you're talking about the NT carb for HT engines.
    Have you tried tightening the nut on the choke lever pivot?

    Maybe you could extend the flat section of the pivot by filing the sides, so that the choke lever seats tighter when the nut is tightened. Hope you know what I mean.
    You'd probably only need to remove about 0.020".
