SU HS6 jet bearing assembly kits
Anyone know where to find these for HS6 carbs tagged AUD 232R? My car has been running all kinds of gimpy lately and the bearing on the front carb is pretty loose. These weren't included in the master rebuild kit and I'd like to find two assemblies before I do the rebuild. I checked my common Volvo parts websites as well as the SU website but found nothing that I'm sure will fit mine.
Any help is appreciated.
Looking at this...

Where did you get the "master rebuild kit"?
For the twin SU HS6 carbs on USA cars '62-'67 the following items are unique to the B18D engine:
#21 - Front and rear jets (they are also different from each other).
#19 - Jet needles (same in both carbs - not spring-loaded).
#14 - Fine coil spring in chamber (color-coded with a paint mark - same in both carbs).
The throttle shaft (#43) pivots on the body of the carb and these two wear-points are the locations of most leaks causing erratic running.
The usual repair is to ream out the carb body then press in a bush of exact OD/ID that will allow a new shaft to pivot freely without leaking.
Sometimes the bush ID must also be re-sized for a perfect fit.
Here is a pic of a spindle repair kit...
What i need are pieces 26-30 in the first diagram. I got my SU kit from ipd. I spent most of last night trying to find ANY other cars that had the same carb setup so that I might could order parts for those cars that would fit mine, but I had no luck. I think MGCs and maybe 144s(?) had HS6s but even from the SU website, I couldn't find any parts that were labeled for AUD 232R tagged carbs.
#26 through #30 are common to all SU HS6 carbs (edit - except some B20). These parts do not move with the motion of the jet and needle and see very little wear.

If you want these items used just buy any ragged-out SU HS6 carb off eBay.

Wow. That's pretty good to hear. If that's the case, I may can find some lying around the shop somewhere. I'm thinking that's what I did last time I had the front carb off but if I remember correctly, the bearing I put on there was from an MGB so it was probably for an HS4 carb.
Thanks for the help George.
232R is a REAR carb - the corresponding front carb is 232F.
I really don't understand what bearing you refer to. I've workd on SU's on and off for over 40 years and do not remember seeing any bearings on them!
You would do yourself a favor to get Haynes' book on SU carbs. Among other things it lists nearly all the different variants and gives good instructions for disassembly, assembly and tuning.
Another source of parts is Joe Curto on Long Island. Since he is in the US it may be easier to order from him. You can google him.
Turns out this is what I need:
Ended up costing around $40 for two kits and shipping to the states. As George said, a little pricey, but at least I can expect the parts to be in good condition.
Looks like I didn't really overpay!
Also, is there a better alternative to these plastic throttle linkage bushings?
I put these in about 7,000 miles ago and one of them has already decided to retire...
OK, I understand what you mean about "Bearing kit". I have never had to replace those ever!
For throttle linkage bushings, I have used plain old rubber grommets. priced approximately zero. They may not last too long but at the price...
Ha, I just call it what they call it. If I referred to it as "that thing on the bottom", well, you ask a stupid question...
For some reason, mine were out of whack so everything in there wasn't lining up like it should.
The plastic linkage bushings kinda suck. They're like $4 each and I got 7k miles out of it.
Lexington is about where US64 and US 70 meet coming from Raleigh, right?

2 1/2 in an Amazon...
Did I say east? I meant west.
