I have also run into this problem, but not with any of my Austin Healeys. =
I have a tri-carb set up on an 1959 AC Ace. When I opened the carbs to chec=
k and add oil, there was only a brass cap with no damper mechanism. Also af=
ter removing the chamber I found no spring and a solid piston rod with no p=
lace to put the oil. Luckily, I have a 2003 SU reference manual for most Br=
itish cars using SU carbs. Each make is broken down by year, type of carb, =
needles etc. but includes all miscellaneous parts like damper, jet, float, =
service kit #s, and more. It listed at 1.9 litre Weller six-cylinder engine=
from 1933- 1952 - all the triple carb set ups. Under damper it states: CAP=
; for piston spring there is no entry. Without going through the whole manu=
al, you can see that many, many pre-1952 cars, such as: Alvis, Aston-Martin=
, Armstorng-Siddeley, Bentley-Rolls Royce, Frazer-Nash have CAP and no spri=
ngs. However, under the listings for all Austin Healey cars (including Spri=
tes) from 1952 - 1974, all carbs on those cars show dampers and springs, wi=
thout exception. This includes 1954-56 100 M Le Mans and 1955-56 100 S 4 cy=
l cars.=C2=A0
As for the CAP unit, the manual shows 7 variants, from plain brass hexagon,=
some knurled brass round and some with stamps for OIL RESERVOIR or THIN OI=
L. They also list 5 different dampers with both brass and plastic caps.=C2=
=A0
I can scan the Austin Healey section and attach for the group, if there is =
interest.
