Carburettor linkage

[Barry153]

Hello All,
Can anyone tell me if my 1964 Mk2 (3.8litre) on SU carbs should have 2 return springs on the linkage or one?
Mine has only one on the throttle lever but i have seen articles where a carburettor spindle return spring is mentioned also.
My engine number is--LC9126-9 and chassis number-- 232487DN
Any help gratefully received.

Hi, Barry,

There should be two return springs. A long one goes from the rear carb to a short bracket attached to the oil filter housing and a shorter one goes from the forward carb to a 'Y' shaped bracket which is itself attached to the carb's two lower attachment studs. I don't think they changed the arrangement to just one spring.

Best wishes,

Ours has two springs as Neil says.

Thanks for your help.
I have now ordered a second spring so we shall see!
I may as well have it right.
Thanks again,
Barry.
