A few years ago as my BJ8 carbs had been so molested over the years by numerous PO's bought a pair of new HD8 from Burlein.
They came with brass capped dampers.For the life of me, cannot see any part numbers on the dampersI am curious/suspicious as seem to have to top up more frequently than I remember with previous SU cars.At least after every 2 tanks of gas driving time.Not accurately checked standing time with no driving.Where does the oil go ? Makes no difference what grade that I use.Thoughts ?rg

The book is free of charge from Burlen/SU. You just pay the
 shipping.Kees Oudesluijs

 and Perry, Both
 of my S.U. books show AUC8112 as the only damper for
 the BJ8AUC8114
 is for the Mk II tri-carb and ALL of the Sprites with the
 exception of the Bugeye (S.U. calls it ‘Frogeye’ as do you
 British listers) which has AUC8103 AUC8115
 is found in the HD8s fitted to E-type Jags and the 4 litre
 Jensen 541 from 1960 – 1963. For
 you Anoraks out there, my main S.U. book by S.U. is called
 pages and is spiral bound.I
 got it at the Goodwood Revival back in 2015.  It is a very
 useful little handbook.It
 has everything you wanted to know about S.U. carburettors,
 but were too afraid to ask.  \uD83D\uDE0A MarkArdmoreNZ From: Perry <healeyguy at aol.com>

 part #s The carbs I have on hand
 have the most common, and perhaps the correct piston rod 
 AUC8112.  Also found AUC8114.  My factory 3000/BJ8 parts
 book covering the HD8 carbs has conveniently disappeared for
 the moment so I can not verify what part the factory called
 for.  The weight of the piston body (very small weight at
 the end of the damper rod) should not have a bearing on the
 operation as it can only move vertically 1/16 inch and is
 otherwise fixed in place. I checked the diameter of the
 piston body on several and they all appear to be the same.
 The diameter would seem to be much more important for proper
 carb operation. I had asked the SU
 dealer in England for guidance for use of the different
 numbered parts but have not heard back, thus this convoluted
 email to the list.P Sent from Mail for Windows 10 From: richard mayor via Healeys

 responses I received it seems that AUC8112 is the correct
 damper for the HD8s.  The main difference between the
 dampers that I can observe appears to be the size of the
 very small weight at the end of the damper rod.  ----------

To: healeys <healeys at autox.team.net> I have 3 sets of HD8
 carburetors all with different dashpot dampers.  AUC8112,
 AUC8114 and AUC8115.  What is the correct damper for a BJ8?
