Mike,
With the very high CT73965 engine number(late TR4A) you should have HS6s...
but that is only if the entire engine was swapped. The H6s have brass
dashpot plunger tops and the HS6s have black plastic tops. The HS6s come
with a left and right hand pair with the float assemblies on outbound
side... while the H6s have the float assembly on the right hand of each carb

Subject: TR3-4 carburetor question
I have a TR4 motor CT73965 in my TR3 TS52320L (btw have the original
5xxxxx series motor frozen up in the corner of the garage). Carbs
appear to be leaking fuel, car is now hard to start, runs a little
rough, so I guess I can't stop myself from rebuilding the
carburetors.
Question: I assume the carbs are H6 model SU's. Could I be wrong
about this? How would I recognize a H6 from an HS6? These carbs
mount to the manifold with 4 bolts, dashpot covers are held down with
3 screws. Can't find more marks on them other than Birmingham and
SU. I think I will order the rebuild kits from TRF, they come with
the Grose jets, so think I will save a few dollars buying from TRF.
I don't have the TRF 4 parts catalog, so don't know if the kits are
different for the H6 and HS6.
Any advice? suggestions? warnings?
Thanks,
Mike/Geezer
