I just drill them out oversized and make bushes to remove the slack in the shaft 😀👍 great video 👍

Hi I’ve just found your channel and loving it , have you done a post on your machine? Is it a bought one or have you made it?

I have known Adrian (AC) for years and he is a decent ordinary bloke with a great sense of humour. However when it comes to all things Mini, SU and Dizzy, its as if he changes into a superhero and pulls his tuning pants on over his trousers! I think he knows more about the A series than the people who originally designed the engine and probably knows more about SU's than SU do. I had an old Land Rover and just for giggles he designed a tuned length induction for its SU, and tweaked the timing and carburation on a rolling road for me. The motor was a different beast after that. I'm old enough to remember when all young men would tinker under the bonnet tuning their cars. From speaking to him now it is obvious that 99% of us did not really have a clue what we were doing! Watching his CZcams videos where he custom grinds needle profiles and adjusts advance springs in distributors is almost voodoo. Coming from a strong engineering background he has questioned and analysed every inch of the mini engine over the years and i doubt that there is anyone else who can match his knowledge. I don't have a mini or anything related but it is extremely entertaining to watch him at work in his videos. If they taught tuning at university, he would be the professor...

Is that a RSP Cooper? Sounds sweet. I notice you seem to have a higher lambda value (leaner on idle) than AC uses, why is that?do you have different location for the lambda sensor in your setup, or do you have different emission standards? Well done on the tuning, another Mini on the road that can be used to its full potential!

Keep the videos coming! A great addition to AC's videos and really motivating!

Hi Darren, are you selling the Powerspark billet 6mm fuel filters? How do I get in touch with you? Thanks, Lin

excellent series, Darren. Nice sequential diagnosis. Well done. Lin

Hi Darren, I have a 45D Powerspark tuned by A.C. Really happy to see that with you we now have a “local” tuner. I am in Florida so not exactly local but at least in the U.S. Also using an HIF 44 prepared by A.C. These are on a 1275 Bugeye that I am restoring for my son. Lin

I love these technical detailed explanations. Well done.

Great video. Could you show how to adjust these settings please.

How did you test how many degrees at what rpm the engine likes?

You sound quite knowledgeable about the details of the ignition. People tend to mix and match all kind of parts on these cars. I would think that heatgrade 5 might be better on a relatively stock engine spec.

So I have one of these in my 1982 Land Rover. The Haynes manual says that the mechanical advance should go as much as 42° at 4500 rpm. But mine has the same cam in as yours with 12° stamped on it. Does that mean that I have the wrong cam? Should it say 42° on the cam? Thanks

AC tuned my car in Feb, still runs like a dream

Nicely demonstrated, you covered a lot of territory and I'm looking forward to future episodes. Thanks Darren.

Powerspark is a cheap Chinese knock off. Fix your original one or find a good used 25D unit.

Thanks for the excellent video. It's RPM not rpm's though. Keep up the great content.

Nice to see someone that knows what they're on about, top work.

Where did you purchase your springs from?

Well demonstrated and explained Darren; thank you.

Sell IT ! astoundingly these POS cars have aquired a resale market price Far And Above any real life value. These were Junk right on their Iron Age assembly line. 50 years Has not helped.

So would the Powersport be more appropriate for say a 998cc?

if the dwell is too long it will overhear the HT coil.

sadly, I've taken the Lucas distributor for granted. This series of videos gives me a much greater appreciation for the intricacies of proper tuning

Great video. Yes please on the 25d and 45d dizzy recurve.

Great, explanatory video; I would very much like to see additional videos with other distributors undergoing recurving. Thank you.

Hi, just replaced the vacuum advance unit, and I couldn t find any info on how so set it up. How many clicks or what should I measure to find a proper set up. Thank you.

Nice work, and thanks for sharing! Do you have a business? How can I get in touch?

Thanks for a good video

Nice job of ferreting out the problem. What would be interesting to me would be putting it back in use and see how it now performs and how long it lasts.

nice workshop manual

Great video. It makes a massive difference to the running of car if your dizzy sorted. I would love to see a video on how you correct an original dizzy and a power spark one. Watching from Nz

There is a big difference between sharing knowledge and bragging that you have knowledge.

Interesting stuff Darren! I'm curious though, what did you do about the loose end and the pin?

So which aftermarket dizzy should we be avoiding? 😬

Very interesting video Darren 👍 where are you based please?

looks like a flame thrower like mine we were talking about

This rather makes the case for closed loop fuelling which normally means EFI. Back in the day I had a BL Montego using the "S" series 1.6litre engine that used a single SU HIF44E carb. This carb used a stepper motor to adjust the main jet location in relation to the needle. It was certainly used to produce a rich mixture for starting i.e. the "choke" and I always wondered if an O2 sensor and full closed loop system was part of the design. I think some V8 Rovers used a similar SU.

Hi Darren, been enjoying your distributor videos and it has helped me learn and progress my restoration of a lotus twin cam which has an odd Lucas distributor - 25D but a body for clockwise rotor while it needs to go anticlockwise. The internals are correct for anticlockwise and there is no shaft wear at all so it is rebuildable without vacuum advance which is what I was planning to do if I replace the plate with a 23D one or lock it up. However, your praise for power spark has made me wonder if that would be a better route. I would need to have it regraphed to suit my cams etc… so was wondering if this is easily done on them (im in Australia and know people with the sun machine) and if there are springs available to do it. Would be a good topic for a video for your channel too.

Nice presentation of the basics; will you be presenting the use of the protractor in a future video?

Interesting about checking the advance with the protractor. I understand about the pointer but where is the stop line to read the amount of degrees to check if it concurs with what's stamped on the cam?

Good information well done.
