For those that may not have come across them, some clever types have been kind enough to share their videos on YouTube, affording us unique views into our beloved internal combustion engines!

Great stuff. Many years ago I worked with a bloke who'd been an apprentice at BSA and he told me about making cylinder heads with quartz windows to look at the flame propagation.

My Dad was an engineer working for a veterinary products and equipment manufacturer and supplier.

The vets asked him to design and make "windows" so that they could view the contents of a cows rumen, so that they could view the digestion process, with differing feeds and also sample the rumen contents to monitor the bacterial species and numbers.

The cows were quite happy, apparently and the vets were delighted. Quite how they did it, I have no idea.

many moons ago, when i rallied my cooper S, i cut a large slot in the distributor, cut a matching piece of perspex and glued it into place.... all this so that i could see the vacuum advance/retard mechanism working ... as i was running a home made electronic ignition i needed the mechanical automatic adjustments to be exact... just saying ..

Steve.. you had me at “cooper S” just the fact that you owned one, let alone rallied one. Respect 🙇???🙇???
In total I’ve owned 12 (original) minis, 2 were mini vans. sadly never a cooper S😢

Micheal ... i owned 2 'S's
a 1071, i had a half share in, and rallied whilst i was in the RAF. once the guy who had the other share got posted we decided to sell it, can't remember how much for... but i see a well sorted 1071S going for £45K !!! hells bells!!
i was determined to have myself a 1275S and get rallying again ... found a write off, severe rear end shunt. bought a mk1 body shell/doors/boot/bonnet, front and back subframes direct from BL, got the local spray shop to paint it in Aubergine... tuned up the engine, bored to 1390, limited slip diff, twin 1/12" reece fish carbs, lightened flywheel, oil cooler, ventilated discs brembo calipers, 5j wheels and flared arches, koni 'ajustarides' etc etc.... was a real pocket rocket and won several rallies in the south west. i was still in the RAF and had loads of time on my hands working shifts on the nimrod flight simulator at RAF St Mawgan. i was also running a dreadful Austin '1100' as a family car ... so, with rallying becoming very expensive and moving off the highway and onto 'special stages' ... and my '1100' becoming an embarrassment, i flogged the 1100 and the 'S' became the family runaround!  :) .. i had to fit a towing bracket to the 'S' as, with 2 growing youngsters holidays required a trailer for all the camping gear etc. my best memory was overtaking an MGC going up snake pass 4 up with a trailer and leaving it for dust!!.... great days .... i did 140k miles in that 'S' flogged it for £700 in 1979, (i recently checked the DVLA, not listed ) and bought a mk2 cortina estate ... i have now gone full circle and got myself a Yaris 'T' Sport .... 20 years old, well sorted and almost as much fun as my old 'S' .... sorry, all this clap trap is very non thumper ...

 ;D ;D ;D

1978 and working in Greystoke Forest, felling and extracting, I had the keys to the gates. The local body shop, sponsored a sprayer with an 'S', similar spec to Steve's and having rebuilt the engine it required some "running in" and tweaking. The Forester, who lived on-site, went on leave for the week! ;)

So, as "navigator"/responsible key holder, after a days work, I locked the gates up, drove back to my caravan abode. Then walked down to the bodyshop, strapped myself in and we went "testing", using the Greystoke RAC stage and others. 100mph + down the main straight, whilst the stones rattled off the sump guard and the whole car twitched and lurched from side to side of the road was exhilerating! ;D ;D ;D  Words are not adequate! :-X

If you want to view old school rallying, then I would suggest that you make a pilgrimage to the Isle of Mull, for the Beatson's Building Supplies Mull Rally. The 2022 rally is pencilled in for the 14th to 16th October 2022 and here is their website link:

I was closely watching the see through carb video and noticed the large fuel droplet is suspended in the air just before the charge of air hits it and breaks it up, it got me thinking, what if you fitted an ultrasonic transducer to the carb body so the ultrasonic waves break up the droplet before the air charge hits it, that would produce even finer droplets that would make the charge even easier to ignite, you could probably increase power and lower fuel consumption a fair bit as well

Please don’t apologise for the rambling Steve. Envious is the word that springs to mind having just read your rally post. Always fancied building a Mk1 with an Arden 8 port head, sadly time, money, doing up houses oh and blinking marriage seem to get in the way. I read that someone now does a 16 valve head conversion using a BMW K100 (flying brick) head. Not cheap but apparently gives decent power gains.... one day, one day 🤞
Cheers, Michael
Ps.. apologies Matt for this thread kind of veering off course slightly 🤔

I have been following this thread with some interest too-all aspects but particularly on the car side.
As some may know i am a regular attendee at Shelsley Walsh and have been known to do a few hillclimb  and sprint "schools" in my sports car.
In recent years we've had quite a few classic rallying enthusiasts going up the hill and there's always a smattering of Mk1 and 2 Escorts, Longbridge minis and lots of others.
My mate who comes to most of the events with me is into classic cars big time and currently runs a 60's mini having owned around 40 of them over the years  and in the last few years an AH Sprite and Mini Sprint (cut down) as well as several MX5's and Porsche Boxsters.
I used to go to watch the Lombard RAC rally in Sutton Park Birmingham in the early 80's when the Quattro's began to rule the roost.
To see something like a Quattro or Metro 6r4 or Lancia Delta Integrale  at full tilt really is something special. To be driving one in (almost) full control must be really satisfying!

Afternoon Martin. I’m a big fan of the mini sprints. Is there any chance of a photo of your mates at some point 🤞🤞
Cheers, Michael

Aye SteveL,

I hope #1 arrives home safe, as the weather is threatening at the moment! Wind not picked up yet, but the tops are starting to disappear into the cloud base, with a touch of the white stuff. That'll be a long old drive back from Kennacraig and better done without the forecast 75mph hooley, up the jacksy!  :(

No doubt there will be something "peaty" in the luggage for yourself!  ;)

Good health, Bill

I'll see what I can do Michael.
I might have one somewhere if not I can ask him.
We went to the Mini day at Shelsley Walsh in August 2019 when they lined the hill with minis.
