petegardner_901 Posted April 5, 2019 Report Share Posted April 5, 2019 Hi Catalogues show an "insulating block gasket" sandwiched between two gaskets on the inlet manifold of each carb. Every parts sales companies say 'not available' any more - only the thin gaskets that go each side of the insulating block. Do I need to worry or can I just fit the thin gaskets without the blocks?

Pete Lewis Posted April 5, 2019 Report Share Posted April 5, 2019 well ukc 490 is there as a heat isolator, so the carbs will take on more engine heat than without. burlen fuel systems show one as part of their rebuild kit , give them a call https://burlen.co.uk/ pete Link to comment Share on other sites More sharing options...
Mad4classics Posted April 5, 2019 Report Share Posted April 5, 2019 Are you refering to the asbestos spacer 147660? Unfortunately Burlen don't produce any spacer blocks for Stombergs, or didn't anyway, even though they make a great variety for SU. When I needed these for my sons car, I approached Mick Dolphin who did have some at the time; don't know if he still has any - listed as rare!

Waynebaby Posted April 5, 2019 Report Share Posted April 5, 2019 A second vote for Trying Mick Dolphin for the asbestos spacers. I bought two off him last year - I don't think I got his last two! Wayne Link to comment Share on other sites More sharing options...
NonMember Posted April 5, 2019 Report Share Posted April 5, 2019 Really? The CD150 asbestos spacers are rare now? Gosh. I probably have some in a drawer from when you used to get a pair with every gasket set. Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted April 6, 2019 Report Share Posted April 6, 2019 Can you not use the SU spacers with minor modifications ? Nick Link to comment Share on other sites More sharing options...
NonMember Posted April 6, 2019 Report Share Posted April 6, 2019 The stud spacing is different and, in my experience last year, the appropriate type of spacer for SUs doesn't exist. LOTS of big thick ones or ones that have designs you can't modify. I was actually looking for SU spacers and ended up modifying some spare Stromberg ones.

Pete Lewis Posted April 6, 2019 Report Share Posted April 6, 2019 would you cut one from MDF with a fret saw ??? or any similar diy material many where just a black plastic, mick dolphin does still list 147660 as 'rare' £3.50p old number like 58923/UKC490/TKC5741 all seem unobtainable i would stiil ask burlen. shown in their kit parts Pete Link to comment Share on other sites More sharing options...
JohnD Posted April 6, 2019 Report Share Posted April 6, 2019 Pete, a small part cut out of MDF and compressed will fall apart. It not deisgned for that sort of use. And heating it releases formaldehyde, which is poisonous. A better bet would be Tufnol or Nylon plate, or even Teflon (PTFE) sheet. All available for not very much on eBay.

Qu1ckn1ck Posted April 6, 2019 Report Share Posted April 6, 2019 Coincidentally, when handing my tatty CD150SE's in at Carburettor Exchange yesterday just one had an insulator block still hermetited to the flange and Dave commented that he would not be able to supply replacement blocks. Is it an elf and safety problem connected with asbestos? Link to comment Share on other sites More sharing options...

Adrian Cooper Posted April 7, 2019 Report Share Posted April 7, 2019 That looks easy enough to reproduce. I could laser cut one in acrylic, plywood or MDF if you think any of those materials would be suitable. Adrian Link to comment Share on other sites More sharing options...

Adrian The spacer advertised in the USA is not necessarily the variant the OP requires but they are all somewhat similar and I guess the correct thin gasket could be used as a template ..... ?

The one in that link has four-stud fixing, which sounds more like an SU HS6 or similar. The UK market 150CD spacer is very simple - a 1.5" hole in the middle and two 5/16" holes equidistant on opposite ends, all in a diamond shape. Some versions of 150CDSE have a notch on one side of the big hole. Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted April 7, 2019 Report Share Posted April 7, 2019 This is pic of an old spacer fitted to 150CDSE carbs to suit my GT6 Mk3, I had not realised they were in such short supply or I would have tried to salvage it 1 Link to comment Share on other sites More sharing options...

Claim it's an "auxilliay balance pipe"😛 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 8, 2019 Report Share Posted April 8, 2019 Strange the strom 125 and 150 have the same part number , presume they are 150 size and the smaller ends up with a stepped joint Pete Link to comment Share on other sites More sharing options...
