I have converted SU HS8 carbs to manual choke so that they operate like SU HS6 carbs. I fit another linkage rod between the front and rear carbs that pulls down both their jets on the choke cycle. This allows me to eliminate the AED unit that would normally sit between the front and rear carbs. I then fit a sliding choke lever on the dashboard, next to the speedo, like on a Jag Mk2 2.4 and 240. There is a kit available that allows you to do this conversion, however I make my own by taking parts from a Rover TC2000 set of carbs and cutting and re-welding the bracket that holds the end of the choke cable. I also have to make a new choke lever with a dog-leg kink in it to fit around the new connecting rod linking the two carbs together that pulls down on the jets. This manual choke conversion allows me to set the jets in just the right place when I starting the engine in very cold weather, and to shut off the choke sooner when engine is up to temperature. There is a video on my channel showing what the manual choke conversion looks like.
Looking forward for the next episode ! Thanks for this very useful video, de-mistifying the job to do on those carburettors. Got 3 on my Jag, it will be much more simple for me with your example !
If you have 3 you probably have an Xk150S or an E-Type. They have SU HD8 instead of the HS8 shown here. There are multiple differences even if the principle is the same.
I hope to get one some day, it is a great tool. this was also part of a larger project where I'm restoring a car at home with tools that most people have at home. Thank you for watching!
Hi Adam, it‘s so nice to watch your videos, espacially to the SU Carb ..., but maybe, it would be possible, that anyone could translate it in german, because there are so much really important details, that I‘m afraid, that I don‘t understand all these details in a right way. Thank You and best regards. Gino
Love your videos. 59 3.4 mk 1 won’t start. I think the choke is not working I hear no hissing. Could it be the vacuum has a leak ? If so how do I find the leak?
I have a 1976 XJ4.2 with two SU carbs - but they appear to have a separate auto choke on each carby - different to what your rebuild videos show - can you explain and advise on this? Tim
Nice Video Adam, maybe you can help me out. I have a Jag S-type 66, with 2 SU HD.6 Carbs. In the middle sits an auxilary starting Carburetter, Afther renewing them and put in some new parts, the gasoline keeps poring out off the starting carburetter and it seems that the carburetter it is connected with does not shut. Any Ideas what might be the problem? I follewed all the instructions from the book. Greetings Arie Zwolle/holland
I have to rebuild my SU's from a 71 240Z. I am unable to remove the top of the float chamber. The screws are out but the gasket is holding the top and bottom together. I am apprehensive about "prying" the top off with a screwdriver or other instrument. The gasket has been squeezed hard enough when the top was put on I cannot get a sharper instrument in between the top and bottom. Any suggestions you may have on separating the top and bottom would be appreciated.
Great video Adam, I've started reconditioning my HS8s last night, but the piston is stuck in and did not want to force it out in case I damage it. It soaked overnight in degreaser and wd40 around the piston. Would you recommend "boiling" the body of the carb as others suggest on youtube? Thanks
You are the absolutely best youtuber calm and cool and Easy to understand.keep up man🥰🚙🚙🚙

about to overhaul my dad's old volvo 240 SU ! .. this vid has been most encouraging !
Best of luck!
Love your videos man! About to rebuild the triple SUs on my manual swapped XJ6. Cheers!
Thank you for a great video

Ove-Norway 420g - the principle remain the same, so it look quite simple !
Excellent and most helpful.
Thank you!
Looks like a really good job for a benchtop ultrasonic cleaner. These are quite low cost these days and do terrific job on carb parts.
I hope to get one some day, it is a great tool. this was also part of a larger project where I'm restoring a car at home with tools that most people have at home. Thank you for watching!
Nice video. I've never had to work on SU's but have four of them so good to know
On multiple cars?
@@LivingWithAClassic yes, Jaguar and Rover
Great little video. Loved it a lot.Aussie.
Thanks for watching!
I got a 1972 MG Miget with dual SU Carbs. Looking forward to your tuning video for them!
Shouldn't be too long until they go back on the car. Thanks for watching!
I've also got a 72 MG Midget that I'm working on rebuilding the carbs!
Favourite and only one is my 240z :)
Really cool cars with a great sound!
I have had several SU carbs. Current project is a Healey Sprite.
We also do some performance mods.
That's great! Which performance mods are you doing?
We currently have 2 sprites. A vintage racing Sebring and a MKII family driven sprite. Too many upgrades and modifications to list here.

MgTd 1953. Can you work on cleaning the carbs while on the car? I have a slow drip from the bottom adjustment screw ( rich/lean) ?
Did you ever film the assembly and initial adjustment of the carbs you rebuilt?

73 240z with early carbs
What if it is still not synchronised after interchanging the pistons?

I tried tye trick of boiling to clean them and I didn't find it too helpful. I hope you can get them lose! I'd try lubrication and temperature changes
Kroil penetrating oil will free anything.
Hi my triumph herald engine dies when choke is pushed back in what’s the cause thanks
How many hours does it take to rebuild the carburetors on a 1963 jaguar mark 2 3.8L ?
Thanks for the videos!
Just a basic clean and re-build maybe 2-3 hours. To polish and all that a bit longer
Hi Adam, have you seen Nitrosilvia's video th-cam.com/video/4QYxGyQy7lw/w-d-xo.html they are also on SU carbs. . Thanks Phil
