[Healeys] carb damper

[David Woerpel]

Must jump in here. Just to muddy the waters a bit, although not relevant to
Big Healeys, the SU H1 carburettor on Morris Minor and Sprite MkI (Frogeye)
do not have piston damper springs. Springs with a red paint splash started
on the MkIIs and Midget MkI.
Carry on, I'm learning a lot!
