What is the collective opinion on the 123 distributor? Two restorers I spoke to a while back (neither outright Alfa specialists) dismissed them as "unnecessary" in a quite pooh-pooh sort of way which struck me at the time as being quite strong. That is a small sample, of course, and the dizzies have been around for a while now so one assumes they sell well.
My thought on that is with any sort of electronic dizzy newly fitted, almost everyone feels a huge improvement.

But, that is mainly because we are replacing a dizzy that other than a new set of points shoved in it once in a while, has never been properly refurbished....I bet every old points dizzy is now worn out to some degree, be it the bearing which would make the dwell angle wander, or the advance springs tired - or vacuum advance etc...

If we took the time to really properly restore the old dizzys in every aspect (or buy a NOS out the box, you'd also feel the difference).....that is a fair amount of work sourcing all correct parts...

I did this to my old 101 Bosch points dizzy (before electronic dizzys were even about) and the improvement was dramatic.

an electronic one is just easier to purchase and drop in and forget about...(well, until the electronic gizmos start going wrong;))

You pretty much sum up both their comments and finish on what most of us probably think! ;)

I suppose I am replacing mine as part of the overall refurb programme... Ive owned the car for quite a few years now and the previous owner had her for 14 years and never replaced the dizzy.. as stated I would think its a case of future proofing the ignition system for the next 20 years as I don't have any plans to part with the car... oh and every one says fit a 123:hehe::hehe::hehe:

Fitted mine a couple of years ago because my old dizzy was a bit worn, and I have a long term plan to replace all potential weak points with items that are less likely to wear and need maintenance; with the 123 its fit and forget, although I do have my old one in the boot because you aren't going to be able to repair a 123 by the roadside if something goes wrong......, having had three mini's I know all about points and condensers but the last one had a 1275 MG Metro engine with an electronic dizzy and that was a revelation compared to the others.
Performance wise there is probably very little between a 123 and a well set up original, however the 123 stays constant and the original wont, for those of us who owned cars with points the e.dizzy would have been a godsend in the day,
I think "unnecessary" is a bit strong, I would say its a "valid option" - up to the buyer really, of course if your running a track car I would say a programmable 123 is essential for squeezing those last few horses out of it.
I'm more than happy with mine

Interesting post Martin. I've been thinking about a 123 but have decide I will fit one of the Pertronix kits available from Classic Alfa. My reason for taking this route is that the electronic module will stay in tune better than points/condenser and if you keep those in the boot, should the module fail you have a get you home. Plus of course it is considerably cheaper than a 123. I should point out that the bearings in my dizzy are OK, if they were otherwise a 123 would be the way to go. If I was going to track day the car, a 123 would be essential.

That was my first route Stephen, i had the Accuspark module but decided to go the whole hog when I discovered the wear in the dizzy, it eliminates the points and condenser which is the weak point of the system

Went to fetch the GT Junior as it has a nice new sexy lightened flywheel which of course is now invisible but I can feel it's effects :) Engine spins up very nicely and certainly more quickly and as I had the synchros changed at the same time gear changing can be as quick as I can physically do it, without the accompanying ''crunch''. It's fine in traffic with smooth pull aways and overall the engine appears to be 'smoother'.

Also, passed her last mandatory MOT, and ironically for the first time the rear wheel bearings did not come up as an advisory!

The mechanic also noted that the mechanical fuel pump was cracked and was launching a jet of high pressure oil rearwards as a kind of chassis lubrication system. Good spot. That could have been a serious issue had it not been spotted.

Gave her a wash today in the heavy drizzle as we are southbound between Christmas and the new year.

Met up with the Welsh crew near Cheddar and had a very wet drive home, top down of course, sadly no other 105's present, apart from a squealing fan belt and crap wiper blades, no probs ...

Drove the GT Jnr from Manchester to Barnstaple and back (not the same day) to visit relatives and to give the other drivers something interesting to look at on the road. Most enjoyable even though it does involve a lot of motorway miles.
I'm about 5 miles from J13 Adrian, you're welcome to drop in for a beak and a coffee any time, although I can't compete with Gloucester services apart from price.....
