Stratton Jimmer Posted April 29, 2022 Report Share Posted April 29, 2022 Having rounded up some bits and pieces including the carb to manifold insulation spacers (which are made of unobtanium), it was time to remove the HS6 SU and fit the CDSE150s.

Stratton Jimmer Posted April 29, 2022 Author Report Share Posted April 29, 2022 Taking off the SUs was the easy bit. What makes this job tricky is starting with a mongrel car. The engine is of unknown origin, the manifold appears to be a late GT6 one, the "new" carbs are CDSE but originated from a large saloon judging by the throttle linkage.

Stratton Jimmer Posted April 29, 2022 Author Report Share Posted April 29, 2022 I ended up with the garden table covered in parts. Some just removed and others from the donor parts (obtained from Symonds Classic Car Components). Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted April 29, 2022 Author Report Share Posted April 29, 2022 The donor manifold was an earlier type with the throttle linkage mounted to a pair of bolt holes the upper hole being where the lower hole of the new manifold is. I figured that I just had to mount that assembly slightly higher and shorten the link rod. Out with the files to extend the mounting plate holes and with a judicious bend and a hacksaw, the assembly should fit. I hadn't counted on the lagging of the exhaust manifold snagging the link so I ground off the offending corner. A snug fit was now possible.

Stratton Jimmer Posted April 29, 2022 Author Report Share Posted April 29, 2022 I now need to get some bits to connect the cables to the carbs. You may have noticed the fuel line has been patched with rubber tube. That was because the metal tubing had two very tiny leaks that only came to light when I manually primed the carbs via the fuel pump. A replacement pipe is now being sought!

Pete Lewis Posted April 29, 2022 Report Share Posted April 29, 2022 do make sure the plunger inside the two temperature compensators are adjusted to be fully closed by tightening the small nut you dont want this open when its supposed to be shut if you fit the gasket upside down you can block the air bypass port for good basic mixture setting it the small delrin washer on the needle should be flush with the base of the air piston Pete 1 Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted May 7, 2022 Author Report Share Posted May 7, 2022 I did as directed by Uncle Pete and she runs and runs better than with the HS6 carbs. (I'm open to offers!) My brother Bob gave me a hand. He has a mk3 Spit. VID_20220507_143848907.mp4 Link to comment Share on other sites More sharing options...

ahebron Posted May 22, 2022 Report Share Posted May 22, 2022 I am glad you found the insulation spacers. If you need to make some then this stuff does a grand job https://en.wikipedia.org/wiki/Novotext I had a pair made for a set of Amal carbs we are fitting to a non-Triumph and the the carbs stay very cool even when the engine is hot. 1 Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted May 31, 2022 Author Report Share Posted May 31, 2022 I now have a NOS (but slightly dented and with some surface rust) air cleaner box which being NOS came complete with gaskets and filters. I also garnered another pair of insulation spacers so if anyone is desperate for a pair, get in touch with me please. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 31, 2022 Report Share Posted May 31, 2022 and to aid cold air we made up some 2" waste pipe , hoping it was better than the convoliuted if you need the flexible go to a pond pump supplier its cheaper than triumph parts the waste pipe bridge peice is just a steady the ends flared witha hot air gun and a big socket Pete 1 Link to comment Share on other sites More sharing options...

It was a Mini that had been in the family for years. The first / early owner was the restorer’s grandad who had one day earlier in the car’s life decided to tart up the engine bay. He’d stripped and polished absolutely everything, including the radiator, which led to the car boiling immediately and another more sensible family member yanking the rad back out and giving it a good coat of black paint again! 1 Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted June 6, 2022 Author Report Share Posted June 6, 2022 Well, the NOS air cleaner box came with only one bolt of the four that are needed to attach it to the carbs. That bolt is a 5/16-18 x 2 1/8" which is I believe, a UNC thread. I managed to find two more identical but aged bolts in my miscellany box (every garage should have one) which probably came from my first Vitesse back in the 1970s. In need of another bolt, I thought I would check my workshop manual (page 0.111) to see what the spec is and was surprised to find that the book lists that bolt as a UNF. Here's the but... 5/16 UNF are 24 TPI while my bolts are 18 TPI which makes them UNC. Is the book wrong? Link to comment Share on other sites More sharing options...
NonMember Posted June 7, 2022 Report Share Posted June 7, 2022 I'm pretty sure the air cleaner bolts are UNC, and I don't recall a torque setting for them (but my 2L manual isn't to hand at the moment) Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 7, 2022 Report Share Posted June 7, 2022 yes believe they were all unc as carbs have the alloy casting to protect from fine thread stripping and that for SU and Stroms the wsm is also wrong says unf ..they are def UNC and torque a hand nip or if you must 6 -8lbft Pete Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted June 8, 2022 Author Report Share Posted June 8, 2022 Thanks both, the WSM says torque as Pete says 6-8 ft lb. That's what I call a "two finger" torque. Link to comment Share on other sites More sharing options...
68vitesse Posted June 8, 2022 Report Share Posted June 8, 2022 The bolts to attach the air cleaner box to the CD150,s on my Vitesse are 5/16 UNF. Regards. Paul. Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 8, 2022 Report Share Posted June 8, 2022 not sure but if its using a nut then the threads have been stripped out or was the nut just to show its thread size ?? its quite unusual to use unf on alloy castings although good old triumph did on the main bearing bridge all mine have been UNC into the carbs all sorts of threads are used to repair overtightened air box fixings including fitting a nut on the back face Pete Link to comment Share on other sites More sharing options...
68vitesse Posted June 8, 2022 Report Share Posted June 8, 2022 Nut just to show size and thread, thread on carbs as Stomberg made them. Regards Paul. Link to comment Share on other sites More sharing options...
