johny Posted November 9, 2019 Report Share Posted November 9, 2019 Pat are you sure theres no other mods to your engine as its strange that someone went to the trouble of modifying the manifold and fitting HS6s without being able to get much benefit ?

Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 you can can use the base carbs just need to check the needles and such the base carb is quite interchangeable its only needles springs and piston weights that get changed the manifold would fit if refaced to make parallel faces ( never tried that ) dont forgat sped tabs get swapped just to use the screws IE the 3693 says its a 1.75" what is the throat diameter ??? on yours ??

PatK Posted November 9, 2019 Author Report Share Posted November 9, 2019 Hi Johny, sadly the car came with no history and I was told that it came from Ireland, North or South I'm not sure. I suspect that the head has been ported and possibly a fast road camshaft fitted as theres not much power below 2,000 revs and then it comes in strong all the way up the rev range. The choke adjustment is also a problem and I can't get it adjusted to run nicely when cold on the choke, so i warm it up on the throttle before driving off. It also has an expensive fully adjustable rose jointed throttle linkage to the carbs which must have cost a bit when installed. It does run rich, the needles are correct, but does not like to idle below 850 rpm. Pete and others have said that Twin Stromberg 150 CDs suit the engine better so I would like to try those. if they work better I will put the SUs on e bay.

Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 yes i viewed this car for Pat and advised it had been HS6 SU'd we had a local car that went through all this and to get it nice reverted to stromberg 150s Pete Link to comment Share on other sites More sharing options...

I think that I will put them on e bay again Pete and then look for the correct Vitesse ones. The car is fine on the SUs so I can take my time, and i now know what to look for. Thanks Pete.

Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 if it wasnt for all the anciliary changes i might have made a bid but , these days it was as triumph intended , i just bought the wrong model year car rust free but has SU's and silly mildest cam of all the range pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 HB prefix its a 1600 but manifold is same as 2ltr, see pic 3 most odd breather set up and not 1600 , closer look there again thats a MK2 2ltr head not a stepped mk1 explains why carbs are CDs150 type choke on front . boot badge holes look it was a vitesse6 that should all work ok make sure what ever manifold you get 1600/MK1 are nothing like the MKII you need Pete Link to comment Share on other sites More sharing options...

Thanks Johny, its in Leeds and we live in Dorset! I also don't have a Facebook account. Pete suggested that as the 2000 manifold and carbs are good, having a little shaved off the intake flanges to bring the front and rear faces parallel would be a solution so this is my fall back position if i can't find a good manifold with / without carbs and a Banjo bolt that the seller has freed up!

I'll go and chat to a local engineering firm next week to see if they could skim a little off the flange faces to make the flanges parallel front to back and at the same time start calling around the Triumph breakers plus e bay.

Yes there was a number under the brass tag, it was pretty mucky but it is as follows, 301, 3693L or 3633L Whats that mean then Doug, triumph 2000? Thanks Doug Pat 3633L and its pair (3633R) were originally Triumph 2000 1973/74 European fitment - 150CD-3 with B5DG needles and Blue springs.
