Did the LJ XU1 have an Accelerator Return Spring connecting the Throttle Rod (my terminology) to the fire wall?

 

While I have your attention, what is the correct position for the carby brass tags?   Front right screw or rear right screw? (When viewed from the front of car)

I have seen some 1972 LJ XU1 with and some without a throttle linkage return spring. However, the Feb 1972 LJ parts catalogue does not list a throttle linkage return spring for XU1, nor for GTR, and 6cyl S & SL models.

The 150 and 175CD carbs have an integral throttle return spring on the throttle shaft and the LJ GTR, S & SL 6cyl engines have a throttle return spring attached to the carburettor so a return spring on the throttle linkage at the firewall was not necessary. The 1973 LJ 6cyl models (incl XU1) had the throttle return spring tab on the firewall ledge just below the heater deleted in production.

All the above said, the LC XU1 had a throttle linkage return spring, the part number is listed in the LC parts catalogues.

 

The brass carby ID tags are located on the front left hand screw as you view the CD stromberg from the side of the car looking over the air cleaner.

Thanks for that information Dave.

 

I had a highly credentialed XU1 engine builder look at my car last week and he said the return spring was missing! News to me. Could not find any reference in any manual. Neither of my XU1s (May 72 Adelaide & November 72 Brisbane) have the tab on the ledge.

 

Conversely, of two LCs I looked at, 1 GTR and 1 I don't know what  dressed up as an XU1 both had the tabs.

 

As for the carby tags, that is where I thought they should be, but a dissenting opinion from a respected source said the front right when viewed from the side so you don't catch it when working in the area. This is serious rivet counting territory!
