Unboxing a NEW set of Triple SU Carburettors

[@kensanity178]

Now, THIS is better than Christmas!.

[@Jibbahrish1]

Brilliant series, excellent editing & no foolish banter. Enjoyed thoroughly. TVM

[@peterfeltham5612]

Yes,great to listen to a man that knows his business,if this were a british show rank stupidity and ego woulď be the order of the day.Oh and I'm english.

[@loloaqici82qb4ipp]

Interesting video. I looked in to Burlen's website and they are the go-to company for this work. And not just SU either. It must be the answer to a restorer's dream to have access to this sort of service.

[@craigpennington1251]

Glad that there is a company that remans this great set up. They look awesome.

[@wcads623]

that is one sweet sounding and looking jag engine!! You guys do a great restoration work on great british classic sports cars.

[@nostology]

It looked like an early Christmas gift.

[@rackburns1]

Richard thanks for such a great series. I am approaching retirement and couldn't decide how to spend the next few years. It was either an early Corvette or a Jag. After your hard word its the Jag for me. I just hope to find the right one to restore. As Earl Crowder used to say " Brent you can't make chicken salad out of chicken sh"""t. thanks BB

Impressive buy from Burlen. My SUs HD-8 (2 inch) do not as nice as these but idle just great at 750 RPMs & are a joy to work with. Of course the EDIS ignition system, no dizzy, brings it all together

[@jeremymasterson5818]

Superb work with outstanding reman parts. Good eye on spotting the fuel leak. If you hadn't you may have discovered the short cut to perfectly tuned SU's. Set the whole rig on fire! I had a'72 XJ6 in which I had done a head rebuild and carb swap from the factory Strombergs to twin 2" SU's. I had dearly wanted triplets but couldn't find any. The morning after finishing the project, I departed on a roadtrip from Toronto to Boston. The carb setup proved very troublesome for the entire trip untill on the way home at a stop in Connecticut, the cold start automatic enrichment device malfunctioned spilling raw fuel everywhere which promptly ignited. A number of tense moments went by while the conflagration was subdued with a borrowed fire extinguisher. I was forced to do a complete dismantle and rebuild at the roadside with a fair amount of improvisation to replace melted parts as there were no repair or parts sources available on a Saturday afternoon in Connecticut for an old British car. Once back on the road, I found that it ran better than it had ever run before and continued to do so for years after. Minus the enrichment device.

[@jeffreygrove5057]

Good to watch the detail again .Love it .

[@henrylauenstein6813]

SU's, Very cool, I had twins on a 62 MG Midget and a big bad ugly on a 62 Rover P6 slant mount 6. Hard to prep but very rewarding.

[@videomaniac108]

I had a 1969 MGB Roadster with wire wheels that had the dual 38mm sidedraft SU carbs and it was interesting to work on them and tune them. Experimenting with mixture needles of different taper, to get the F/A ratio exactly right, was an interesting task. I would also fill in jet orifices with solder and then drill them out with tiny hand-turned drill bits for exact mixture control. I used to use a UniSyn meter for synchronizing carbs on my bikes and the MGB and Austin Healy that I owned. On my bike that had an individual carb for each cylinder, I would rough set the balance with either a UniSyn or measure intake port vacuum on each cylinder. I would then fine tune the carbs by doing a power balance test, where I would short individual cylinders an adjust the throttle butterflies for equal RPM drop from each cylinder.

[@RichardMichaelOwen]

Wow you had tuning down to a science!

[@ericheine2414]

That was really fun to watch. Yes, I'm jealous, and I want one.

[@scottparis6355]

They come in a $190 Pelican case! Class act. And when you've installed the carbs, you can use the case for tools or weapons or $2 million in small bills.

[@tekoppentekoppen761]

Dude those pelicans are from 300 and up!

[@colinblankenship2401]

smooth sounding engine. One of my favorites

[@sonyhk3824]

So beautiful sounds, great job guys. Cheers

[@NialPowerCork]

Wowser I feel a little bit light headed! Going to have to go for a lie down🤣🤣

[@paulhay8781]

very nice mate thats a great job. Brilliant in fact

[@dwtees]

If you have to ask how much those carbs cost you can't afford it. I've never seen anything with SU carbs idle that smooth in the 45 years I've been a tech. Nice work.

[@jrichker]

Synchronizing SU type carburetors - It isn’t hard to do at all, and the homemade tools are very inexpensive and easy to make. You need 3 each 6” x1/4” wood dowels; in a pinch 3 good wood pencils will do nicely. Clean the dowels (or pencils) up so that both ends are flat and there are no splinters or bits of wood that can fall off and cause problems. The hardest part of the job is to suck out any oil from the dampener pistons so that the dowels don't float in the oil. Remove the dampeners from the carburetors and insert the wood dowels, pressing down on them until they bottom out. Take a knife and score the wood dowels using the top of the piston housing where the dampers screw in as a resting point for the side of the knife. Twist the dowels while holding the knife edge against them to make a small groove all the way around the dowels. That groove is our zero mark and starting point for our engine running test. Next, start the engine and note the distance of the marks above the top of the piston housing. Adjust the idle speed stop screw on each carburetor so that all 3 marks are at the same level above the top of the piston housing where the dampeners screw in and at the desired idle speed. A 6” General Tool stainless steel ruler works well for those who need a visual aid in getting all 3 marks to the same distance above the piston housing where the dampeners screw in. As you push down the accelerator, you will notice that once properly adjusted, the marks on the 3 dowels maintain the same distance above the piston housing where the dampeners screw in.

[@RichardMichaelOwen]

Neat process I assume this in lieu of a Uni-Syn Carburetor Synchronizer?

[@jrichker]

YES. It works on any number of SU carburetors until you run out of wooden pencils to sacrifice... :LOL It allows you to see what all the carburetors are doing in real time. No need to move the Uni-Syn and then find that after adjusting one carburetor that the other carburetors need adjusting.

[@nzsaltflatsracer8054]

I did my apprenticeship on Jag, Daimler & Rolls back in the day in NZ & put 2" SU's on a lot of different engines. I actually have one on my VW experimental aircraft engine now & 4 on a Continental O-720-8 that is destined for a street rod. Those suckers are getting hard to find now.

[@RichardMichaelOwen]

Continental O-720-8!! would very much like to see that.

[@nzsaltflatsracer8054]

@@RichardMichaelOwen They are a really rare engine & I got mine from a farmer who had it as a spare for his Ag plane crop duster that was long gone, I actually traded some work for it. It was new with zero hours but minus the fuel injection & covered in hay dust in a barn. I built a center plenum box for the SU's. Here's the only pic of one I could find online that has the crossflow heads like mine. gulfstreamaviationcompany.com/

[@kevinchamberlain7928]

Love the Skinner Union carb packaging!!! It inspires confidence! Wonder if the weaker Strombergs do a similar thing?

[@markmathews6876]

nice looking engine boys ,well done

[@jeanhawken4482]

Looks special

[@RichardTomkins]

So if the clearance is bad on that float bowel adapter, then you should check the clearance on the other two to avoid problems.

[@RichardMichaelOwen]

Never seen this problem before. We let Burlen's know, I think they saw the video so it shouldn't happen again.

[@westschleife]

lol@'unopen this box'. So you closed it? Great video.

[@06retd22]

Those are beautiful; impressive packaging. Save the case for when you need to return them. Just kidding; I love my brit cars.

[@rockinrowdy13]

I really could use one of those carbs for my vintage 1948 Harley-Davidson Panhead.. :-)

God Bless the UK 🇬🇧

[@stevejones9062]

Tuning triples was seen as a dark art only known to the chief mechanic

[@Oldbmwr100rs]

Only slightly more effort than tuning twin SU's really. One of those things you have to wrap your head around the first time, and really study the instructions. Once you understand how these simple carbs work it becomes pretty easy. There again I've got over 30 years in motorcycle work and am quite used to multiple carb setups.

[@ldnwholesale8552]

Actually quite simple. To set proper mixtures can really only be done on a dyno. But the rest is quite simple provided you have a good linkage set up. The 2" though are quite a bit different to the 1 3/4 Austin 1800 mk1 carbs that many use in triple carb set ups for many 6 cyl engines. That original aircleaner box though is bad news for power, almost a choke. And tuning must be done with that air restriction on. I use a filter about that size for each carb straight on the carb. The main reason is to go over the ramtubes which give a little more power and better mid range grunt [torque]

[@pauloconnor7951]

Magnifique !

[@keitht2045]

I dread to think what they cost!!

P.S. No engine hide cover for this beauty. These engines sound great with glass packs.

[@staxter6]

How do you un-open a box? Nice set you got there.

[@RichardTomkins]

Seeing as how you Hearted my comment, I will share a secret technique with you and all your followers. How to avoid cross threading a screw, nut or bolt, and how to retain structural integrity in plastic when re-installing screws. Always, lightly back the screw, nut or bolt in the reverse direction of the thread. As you slowly turn the screw, nut or bolt backwards, as the threads of the two pieces come together, the screw, nut or bolt, will drop into the other piece, usually you will also hear a click. It is at this point that you have mated the two pieces so thta when you apply rotation in the proper direction, you will not cross thread the screw, nut or bolt. For everyone that has to remove screws from plastic objects repair what is inside the enclosure and then re-insert the screw, and maintain the strength of the original fitment, this technique should always be done. If you simply start turning the screws back into the plastic, you will cut new threads and reduce the structural integrity of your product by as much as 50%. Further, you will not get a third kick at the can, as the thread in the plastic almost always strips on the third attempt. Happy screwing people! ;-)

[@jeffallen2923]

Case is nice! Free toolbox! So what did you do with the packing? Too nice to throw away. I remember buying two 1 3/4" SU's brand new for $25 the pair at an auto show here in OZ a while back. When British Leyland stopped making the P76 (Google it...) they sold all the bits very cheap. Cant get over how smooth that engine is.

[@pablocespedes9585]

Just give me that damn box of the "carbureters" and I'll be happy!

[@dwightbrown2808]

How do SU's compare to Webers? I had a Datsun 240z with triple Webers. I miss it still. I have gone to the dark side and drive a pushrod V8 now (Chevy LT1 direct injection in a C7 Corvette).

[@GearheadOutlaw]

A headache to maintain after they get worn out

[@dwightbrown2808]

@@GearheadOutlaw Which? the SUs or the Webers? It was always my impression that Webers were the top of the heap given that they were used in race cars (Ferraris, etc.) But I have always had a soft spot for SU.

[@GearheadOutlaw]

@@dwightbrown2808 was talking about the SUs. My series 1.5 has 3 and I'm over the fence for webers and at the same time want it to remain original.

[@RichardMichaelOwen]

Webers are far superior in the corners, must be the float bowl design? Not sure.

[@GearheadOutlaw]

@@RichardMichaelOwen you could have a look here as it sums up the technical differences between the two. www.mossmotoring.com/carburetors-su-vs-weber/

[@tonyeezi7315]

Almost seems a shame to keep those carbs hidden under the bonnet (hood) . . . almost :)

[@johnnymac26]

lol I remember people saying use brake fluid instead of oil for the dashpots on an su carb as it doesn't rot the diaphragm and also made them more responsive as its thinner,,,,,hmmm?

[@martingoode2881]

I think you are confusing SU carbs with Stromberg, the diaphragm on a SU is only in contact with the fuel, the Stromberg has a different set up, although I will agree that using brake fluid in the dashpot might make them responsive but the correct oil is there for a reason, to enrich the mixture on acceleration.

[@johnnymac26]

Maybe has been a long time

[@nexpro6985]

I seem to remember being told to put automatic transmission fluid in the dashpots on SUs. They seemed to run fine.

[@jtorralb]

I went with the triple SU's from Weber DCOE 40's on my TR6. Not to compare it with the E. Not even in the same ball park. But, regardless, I could not be happier. Some pictures here www.roadsterdrivers.com/album/4

[@SPfg3388]

I would guess that is about a $7k plus item.

[@RichardTomkins]

Wrong size screwdriver for the adjustment. When the proper sized tools are used, they do not slip out and scratch the metal, fall out of your hand or cause you to scrape your knuckles.

[@ljuberzy]

what's the name of that tool at 11-20?

[@Hawlkeye-e9p]

What? No dyno pull?
