The wisconsin pdf file I downloaded lists the carbs for the older engines. It groups a one cylinder, TRA10?, the thd/tjd 2 cyl, and the V4 engine. Lists only one zenith model for those 3 groups of engines. That model has 3 venturi/discharge/jets sizes but does not say which engine each is for. Small, medium, large so I assume the small fits the one cylinder and the medium fits the tjd/thd engines.

I have not put one from a tjd/thd on a 154 but have put one on a 185. Worked so I assume a 154 would get the same results. The carb linkage may not fit and the throttle plate may bump the intake manifold hole. The carb itself in terms of the venturi and so on should work. Since you have the carb then I would try it and see if it works.

Thanks Landreo. I did get it to run fairly well on the Int. carb so probably wont get to work on it till it warms up after maple syrup season. But thanks again for the info. Harold
