[TR] TR4

[keithstewart at bell.net]

TR4s started with SU H6 carbs, did a trial run of ZS carbs (1000 I think), then went back to H6s before they switched to ZS for a longer run. Eventually the ZS carbs were replaced by the SU HS6 carb for the rest of the TR4A run. Somewhere in my notes I have the dates and the VIN numbers. I am happy to dig them out if anyone really cares 😊 I have the H6 carbs on my 57 TR3 (John Swauger’s uncle’s car) and HS6 carbs on my 62 TR4 and 67 TR4A. Obviously the HS6 carbs are not original to this early TR4.

Here is an interesting video of a TR4 engine refresh.  Wish I could do it that quickly!!!

it look like an early car – it has the round engine mounts, but it also has ZS carbs.

 

Clearly I was wrong – I thought the ZS didn’t appear until the TR4a
