If the mixer on the top of the carby is Impco, then you should have an Impco LPG converter as well.
Apparently, both TB42 carby and RB30 carby use the same converter.(Correct me if I'm wrong).
I always wondered whether that's the right setup. Two engines behave differently due to different sizes, although they both use the same carby with minor tweaks.
