Lamborghini Miura - Tracing a running fault to a 17th century invention | Tyrrell's Classic Workshop

This stunning Lamborghini Miura finished in Blue Speciale was lovingly restored by Iain and his team 4 years ago. It has returned for a service but has a running fault that Iain suspects may be as simple as stale fuel after low recent usage. After some detective work, Iain identifies the real culprit, whose technology can be traced back to a 17th century invention for windmills that would then form an integral part of steam engines!
Iain sets to work on rectifying the issue, before piecing everything back together for a quick tune up, before taking her out for a road test to see if the running fault has been resolved.

One of the things I love the most about this channel is that not only is the content really good, but while you listen to Mr. Tyrrell saying all of these interesting things, there's all this stuff in the background as well! No need to make up a set or travel to a location-just film in the workshop. I love how there's always an interesting Diablo, or a casual Ferrari (or Harry Metcalfe's Espada!) in the back of shot. It's a way better setting than just about any KZbin channel could ever manage, regardless of how big their budget is.

[@x.x..x.x]

You nailed it on all counts!

[@stanislavczebinski994]

One could argue Jay Leno has more interesting stuff in the background - but he has obviously different resources, so to speak.

[@daniel2001]

Every time Ian gets to put his foot down in a car that he's sorted the engine on, there's that excited "WOOOO" and a massive grin. The love of cars (and driving them) really shows through.

[@BasilBadger]

I think I would have used a plain grease or perhaps MoS2 grease. Copper grease isn't really meant for parts that are "rubbing". But great video as always 🙂

[@Milo_Minderbinder]

Exactly my findings, too. (...in over 40 ys)

[@ypaulyuk1]

I thought the same, the copper stuff is abrasive and will cause the parts to wear quickers

[@stuarthicks2696]

I’ve seen those distributors for decades and never had ANY idea how they worked. This video gave me a glimpse. Thank you.

[@liverpoolscottish6430]

The Miura V12 symphony orchestra!! What a stunning machine on every level. Just EPIC. Many thanks for sharing Iain- fabulous!

[@chrisroach9459]

The distributor work and education was wonderful, but Iain, I must say, the pure joy of driving that car is so clearly coming through to the viewer. Just glorious. Thank you for bringing us along.

[@fteoOpty64]

The smile on Ian's face when he guns the car just made my day!. Yes, do feel like a 16 year old pushing dad's convertible on a covert drive while he was away....

[@blackbuttecruizr]

That smile when it accelerates... Priceless.

[@SerbanCMusca-ut8ny]

I've rarely been more enthousiastic. My God, that engine sound is such music to my ears! From the bottom of my heart, thank you for making these videos.

[@ronmoore5632]

Remember years ago, you could get T/Shirts, Mugs, etc with the slogan `GENIUS AT WORK`.....Never has anything been so adept.....Someone please find Iain a T/Shirt or Mug !!!!! I could watch and listen to Iain for hours, Iain you need to write an Autobiography of your life !!!

[@C.Fecteau-AU-MJ13]

Iain is the definitive master of his art... Genius, combined with an obsessive devotion to excellence and the ability to assemble a team up to his standards, are what separates the best of them from the rest them. If I manage to get even half as good at my work, as Mr Tyrrell is at his. I shall leave this world one very satisfied man.

[@markevns9983]

When your engineer uses a paint brush you know you're on to a winner. Very educational Thank you.

[@colinashby3775]

That engine was the quietest engine I have heard in ages. It sounded like no lash at all. Smooth and quiet.

[@chrisg1592]

Someone recently proposed the question ‘In the era of electric cars, what would you do with your last tank of petrol?’. I think the last 90 seconds of this video answers that question.

[@NLBassist]

What a brillinat vid again. Nothing is more relaxing (and educating) as having a good glass of red wine and listen to Iain explain stuff. Thanks!

[@cryalowicki]

5:23 in one sentence you've explained spark advance in an understandable way. In my 20 year of 'car enthusiasm', I've never understood it so clearly. Thank you Tyrrell.

[@kevinsnowdon9797]

I've another 20 years on you and totally agree with you. It's so simple when Mr T explained it.

[@LOTPOR0402]

Thats because 20 years ago dizzys were a thing of the past in cars

[@andy-james-]

I had a similar moment a while back when Iain explained he was putting cheap, nasty oil in a rebuilt engine. I was initially horrified thinking it should be super duper synthetic, but cheap nasty oil he explained allows the mating surfaces to bed in properly! Then after it's been run on they will swap to the good stuff. It all makes sense now.

[@PiDsPagePrototypes]

Ian did it so well, but didn't even touch on how changing the springs and weights can change the advance curve, or how the changes in fuels from the 1960's to now means cars like the Miura need completely different curves to what they left the factory with, or how combining those mechanical advance units with a good vacuum advance gives a load dependent ignition curve, which modern computer based systems use many more sensors and some very complex coding to match. The real advantage of the modern systems, is that they are far more maintenance-free then older methods.

[@LOTPOR0402]

[@simonsackett]

I'd be more than happy to watch a detailed tune up from start to finish.

[@Kaptain13Gonzo]

I love it: "the loud pedal". That's some ear & touch to set up all 12 carbs. Just a wee twist to each, not too rich, and make the engine burble away. No laptop and some whiz-bang internet download. That is engine tuning at its finest. A joy to watch.

[@graham6229]

Now that is a true 12 cylinder engine sound. Racy, growly, spitting and spinning. Great video Maestro.

[@Gorgonzola001]

The video shots of the V12 without the rear bodywork are magnificent. Then cutting away to Mr. Tyrrell's big smile behind the wheel to match our own. Kudos to the videographer.

[@iain_tyrrell]

Our Videographer, Jonathan Whipp is excellent indeed! Thank you for those words have duly passed them on to him.

[@iainmacleod4007]

Had that problem on the Lucas DMBZ6 distributor on my Mark 2 Jaguar. I also had fitted Pertronix electronic ignition and Lucas Sports coil (in gold). Had to replace HT leads, distributor cap and rotor arm to prevent the very high voltage spark tracking though. Once sorted out went like the clappers though as fuel combustion became more efficient and the twin SU’ s became far easier to tune.

[@mattsansom644]

Someone that truly enjoys his job and shares that pleasure with us. Nothing else on KZbin is so relaxing and thrilling at the same time!

[@kevindimauro9689]

Well put. Relaxing and thrilling at the same time. Definitely knows what’s what.

[@nunoalexandre6408]

True!!!

[@randomsurfer3963]

The sight of a Miura driving around with its rear clamshell off and engine exposed to the elements , must have been quite something for others to see..excellent episode once again! Thoroughly enjoyed every minute..

[@MrPahankeisari]

I was worried about rear wheel throwing rocks to the carbs.

[@raypace2885]

OMG! The end of the video was fantastic! The sound!!!!! Take care of yourself Iain, we need you.

[@timcameron9023]

That's the most beautiful Miura I've ever seen, what a colour. Great video.

[@mosca3289]

That shot of the carbs and throttle linkage at work was awesome.

[@weofnjieofing]

Well done Iain! That sound was glorious! No greater symphony than a Classic Lamborghini V12 with quad triple choke Webers!

[@thomasmulhall4873]

Grazie! Grazie Mille! What a treat to listen to Iain's narration, then those carburettors! Placing the camera inside the engine compartment is such a kingly gift for any enthusuast. Thank you, you made my month....

[@GM-fh5jp]

All things aside...can you imagine what those little contacts must be made of to withstand the constant opening and closing each revolution of the shaft? Tough little buggers... *This must be one of the very few channels on KZbin that a "dislike" could not be justified :)

[@Tuberuser187]

I think I just fell a little more in love with the Miura, how mechanical it is.

[@RandyWillcox]

The mini Miura keychain at 15:26. Gotta love it! The most beautiful car ever made, in my eyes. Luckily, at 6'2", knowing I can't really drive one helps accept the fact I'll likely never be able to own one. 😂

[@paynebabes123]

My father walked in and thought I was watching Keir Starmer show off his car!! Great video as always.

[@mobiledevto]

One of the best channels on youtube for petrol-heads. Love to see an episode on your story, your car history and how you got started in restoring cars. And lastly, love to see an episode on refreshing, installing and tuning a weber carb.

O M G … that V12 sound is an incredible RUSH!

[@michaelsummerell8618]

"Every day's a school day" - Love Iain's humility and amiable manner - like the best kind of teacher we all wish we'd had! Also, the step-up in camera work really noticeable on this video with the engine shots and driving sequence at the end. Superb stuff. Many thanks as always.

Another content creator making "mainstream" media programming BS obsolete, and good riddance to it!

[@13Pandam]

He must have driven it without the rear bodywork to get those engine shots!

[@CubeCyclone]

What a beautiful restoration... Interestingly the most modern upgrade is the bit that let it down. Superb example of Italian craftsmanship in the hands of a well seasoned oldskool British engineer. What a peach that car is !

[@keithwelton]

I well remember drooling over Lamborghini’s at the London motor show around 1970 and being amazed at all those carburettors, that reminds me I must get out into the garage and service my lawnmower ready for the first cut of the year.

[@jferro113]

As someone who is just starting Their life as a automotive tech it's my dream to work on vintage Italian cars and this was a real joy to discover

[@Jesse-B]

As a faithful viewer, I love all your shows Iain, but this in particular is one of my favourites; you doing what you do best, tracking down problems and literally optimising classic bits of gear. I still love your test drives and stories though.

[@MichaelCoburn]

I could really watch this endlessly. What a master. Good job Iain! Can't wait to see the work proceed on Harry's Countach.

[@Slimboid]

I'm looking forward to the runabouts and suvs in all having a gentle whine in my neigbourhood. I'm sick of the fumes and noise in London. It's a depression of constant asthmatic exhaust notes. Iain's cars are symphonic rare beauties. They'll be loved and cared for (lord knows his customers have the cash!), running on biofuel - occasional music for the soul while 99.99% of the rest of the boring ICEs in the world go the way of the dodo. Happy days that can't come quickly enough.

Takes me back to the carburetors & distributors I worked on in my early cars--though truth be told I enjoy the convenience of my current efi.

There is always a focus at any car garage.🤣🤣🤣

[@piccalillipit9211]

I believe that 72% of all Muira's in the world are in a garage at any given moment in time. 12% are broken down waiting to be recovered. 6% are on their way to a garage and 10% are running brilliantly.

What more can one say. It's almost an ownership experience watching your films, as you are seemingly talking to 'me' about my Miura's problems - if only.

[@stevewilliams7956]

This sort of video is why I subscribed. I love the problem solving and explaining of the whole situation and history of it.

[@sabeelra]

Harry and tyrrell killed it this week. Both awesome videos!

[@NigelMarston]

Fascinating mechanical solution but when you compare mechanical points and carbs to modern electronic ignition and injection, you can see just how far we've come since these were the standard. The gains in power AND fuel efficiency with the modern hardware are quite significant. However there is a lovely sense of satisfaction seeing how it all works in the mechanical solutions.

[@stephenmurray9850]

What a great sound of a V12 going to nearly red line and back down again. Love it ,

[@TIMMEH19991]

There's something just glorious about the sound of a weber carburettor.

[@craiggreen4388]

Fantastic video once again Iain. Great sound footage of those carbs too. The video was all the better for the effort it took to capture.

[@Auraxium]

The 'Testing the Loud Pedal' chapter was very well done. Filming and editing really spot on.

[@davey_projects2977]

I find Carbs and mech/vacuum dizzy cars quite satisfying to work on. Arguably quite simple with a few key things to get correct. And once setup correctly they do give very good service. Even points work quite well, though electronic is a nice option. Pretty damn rare to break a spring though!

[@GTE_Channel]

As a kid I grew up with the Countach. I would kill to drive one, but somehow an opportunity to ride shotgun in this would be on top of my bucketlist.
