PatK Posted November 8, 2019 Report Share Posted November 8, 2019 Hi All, I have just bought an inlet manifold with twin Stromberg 150 carbs, for my 2L Vitesse Mk2. The car has twin SU HS6's which I think are too large for this engine although it does run fine but Pete and others have said that Strombergs are best so I thought that I would try and fit a pair this winter. The seller said that these would fit a triumph 2000, GT6 and Vitesse, however both the manifold and the carbs are different to the one that I have which is in a very sorry state ( my carbs are OK but the manifold is damaged beyond economic repair ) From the photos below there seems to be only a choke on the front carb, and apart from the fuel line tubes there are another 2 tubes on each carb, I'm guessing that the larger tubes are for crankcase fumes as there is no port on top of the manifold to take fumes from the Smiths breather valve. The other 2 tubes are of quite a small diameter, but I've no idea what they are for, and what is the large black rubber hose with a plastic end with small holes in for? Is this set up for a 2000 or late GT6 and could i fit it to my 2L Vitesse? Any advice and help would be much appreciated, Thanks. PatK Link to comment Share on other sites More sharing options...
johny Posted November 8, 2019 Report Share Posted November 8, 2019 cant answer all those but the large hose is for a brake servo and can be blocked off if not required... Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 8, 2019 Report Share Posted November 8, 2019 CDS 150 . single choke starting valve on front and tube to feed choke to rear carb. adustment under float bowl good start need to check the needles and piston weights if manifold from big saloon it wont work, wrong angles etc as saloon engine is canted like 15 degrees. pete Link to comment Share on other sites More sharing options...
Paulfc Posted November 8, 2019 Report Share Posted November 8, 2019 Hi, Are there any other numbers other than the A951 anywhere on the carbs? Paul Link to comment Share on other sites More sharing options...

Paul Hi Paul, I will look and let you know but there are no numbers on the front of the carbs, but there are some numbers stamped on the intake flanges.

Are the 2 small tubes for connecting to the crankcase breather? Link to comment Share on other sites More sharing options...
johny Posted November 8, 2019 Report Share Posted November 8, 2019 can see why youd want a servo on the Vitesse although Ive gone to a 3/4" master cylinder and original asbestos brake pads and now find the stopping pretty good. On your carbs I think the larger connections might be for the rocker box vent and the little metal tag fixed on the top of the front carb should give some useful numbers....

PatK Posted November 8, 2019 Author Report Share Posted November 8, 2019 Thanks Johny, thats useful info, I'm still wondering what car they came from. The manifold does have a Stanpart number on it and There is a small brass tag on the front carb, but I can't see any number on it, but I will have a good look tomorrow, when I go out to the garage again.

johny Posted November 8, 2019 Report Share Posted November 8, 2019 The tag was originally stamped up and theyre usually lost over the years but if not the number can still be difficult to read.... Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 its a saloon manifold , you will find this tilts the carbs away from vertical so no i dont think it will work , makes them so high they foul the bonnet the plastic stubs are to take a sealed breathing hoses off a tee piece from the rocker cover the cap s sealed not vented you could plug or re use has your orig manifold been modified to take the HS6 or it was from another triumf.

Pete Thanks Pete, my original manifold has been modified to take the HS6s, so I guess that my best bet is to put these carbs plus manifold back on e bay and look for a Vitesse 2L manifold, unless someone in the club has a spare one for sale.

Doug Thanks Doug, you must have a good little eye! 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?

Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 i wondered about mine on the 2000 as the outlet stub had corroded , but against all vibes the bolt un nipped and screwed out by hand nice new shiny brass one now fitted so not all are a real pig, Pete Link to comment Share on other sites More sharing options...
PatK Posted November 9, 2019 Author Report Share Posted November 9, 2019 Yes Pete, this guy luckily removed the Banjo bolt before he sent the Manifold and also included a serviceable 2nd hand bolt. I also notice from this manifold Pete that the top of it where the Vitesse temperature sender would screw in is blanked off with a plug, so i could not fit the sender there. So back onto e bay it goes! Thanks Pete Pat Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 9, 2019 Report Share Posted November 9, 2019 Pat, the temp sender is or should be fitted in a port in the thremostat housing , this has two outlets one to heat the manifolds one oposite for sender never seen one in the manifold ???
