RBW Posted November 23, 2022 Share Posted November 23, 2022 Hi Phil, I have a 1960 US TR3A fitted with Strombergs, and they are not working well, despite a rebuild with new needles. The mechanic said I needed SUs, but I thought he said 1.5inch, not 1.75. Would these HS6 carbs work for my TR3A with the larger 2.2 engine? Will they need a lot of work? I haven't joined the club yet, but I was going to join the TR Drivers' Club or the TR Register. But they don't have the membership or the choice of spares of Club Triumph. Could you let me know if these will work for me? Best wishes, Richard Quote Link to comment Share on other sites More sharing options...
RBW Posted November 24, 2022 Share Posted November 24, 2022 The mechanic said: "if possible can you get the numbers on the tag it should be on one of the float chamber screws" This will give him what he needs to check whether correct size needles are available. Can you find this for us? Quote Link to comment Share on other sites More sharing options...
mikeyb Posted November 24, 2022 Share Posted November 24, 2022 Not my carbs so I may be wrong - but are the numbers quoted in the first post, those from the tags? Quote Link to comment Share on other sites More sharing options...
Tim Hunt Posted November 24, 2022 Share Posted November 24, 2022 Richard, My TR4A had HS6 carbs from new, tags under float chamber screws read AUD 209F and AUD 209R (Front and Rear). I am sure these carbs would be ideal for your car as it has the larger engine (same as my 4A). The codes Phil quotes are correct for the HS6s as fitted to the TR7. I have no idea how similar these are to the earlier ones and whether they would be adaptable for your car. I suggest you check with Burlen, THE SU specialists, on 01722 412500.

RBW Posted December 2, 2022 Share Posted December 2, 2022 Thank you for your replies and helpful suggestions. I spoke to Chris at Burlen, and he said he thought the HS6 carbs fitted to the TR7 had 'a different profile' from the earlier ones for the TR3A. He has some HS6s 1.75 inch for the 2138cc engine. Unfortunately, they are £868.25 plus VAT. I am also waiting to hear from Southern Carburettors whether they think the TR7 ones will fit. And also waiting to hear from Phil, what the tag numbers are, and if these carbs are still available. Does anyone have any other ideas? If not, I might have to buy the new ones from Burlen. I have to get the car running properly, after all. Thanks again. Richard Quote Link to comment Share on other sites More sharing options...
Rob Fenton Posted December 3, 2022 Share Posted December 3, 2022 I have a pair of fully refurbished HS6 carbs for sale. They cost £600 just for the refurb. They are not exactly the same as the photo above, the bottom of the jets look different. Whether mine are right or the others are correct I don't know, but for purists I'm sure they can be easily and cheaply exchanged. Please contact me if you are interested and I can send photos.

RBW Posted December 3, 2022 Share Posted December 3, 2022 Yes, I am interested. Could you tell me what the serial numbers on the tags are? Quote Link to comment Share on other sites More sharing options...
Phil Townsend Posted January 25, 2023 Author Share Posted January 25, 2023 Sorry for the delay in getting back, illness ruled for a while. The tag numbers are as quoted in the first post, ie FZX1242R and FZX1242F , and the carbs are still available. Quote Link to comment Share on other sites More sharing options...
