I have a Weber 32/36 DGV (manual choke) carb on the 1600 crossflow engine in my 4/4. Currently it only has one throttle return spring, and that is not secured (imho) in a particularly elegant manner.

Can anyone tell me if one or two springs are normal (I would have thought two were safer) and show me a diagram or pic of how the lower end of the throttle return springs are correctly secured?

many thanks

Got the standard return spring in the carb, and then the additional vertical one you can see in this photo. Spring is an MGB/C throttle spring which goes from the throttle assembly on the carb to a very rudimentary bottom bracket. Will probably fabricate something better at some point.

Secondary throttle cables should ideally be a compression spring over the exposed inner throttle cable, additional extension springs on the carb linkage are likely to put extra load on throttle spindle increasing wear.

RHD 1970 Not my car in photos but my '69 has exactly the same fitment,
only one return spring and it is attached to the rad. stay-rod by simply inserting the open end loop over it.

It's interesting that Bert's works in the opposite way to mine. I certainly don't have that bar that goes to the radiator either. However, the metal bracket that holds the cable adjuster is the same as mine, although mine is in the rear of the carb (by the rocker cover).

Bruce's works the same as mine, although looks like one of the weber linkage kits has been added Linkage Kit
