Hi,
I dismantled the SU's on a 52 R type and no damper springs on the piston
Any reason for this and if not what colour code springs are fitted as standard
I really am cursing the previous owner

There are no springs, that's how they are.

Damper springs were fitted to R type carburettors, but only those with Alloy damper pistons, when the damper valve was modified slightly.

R Type carburettors with bronze / brass damper pistons had no springs fitted.

Less mass with the aluminium damper pistons, hence the spring.
