Thanks for calling me a fool

My car has a new battery-3weeks old
New HT leads
123ignition
Admittedly the timing is slightly retarded-I'll get that put right.
With just over 200,000miles on original, untouched engine, I think it's probably time to give the inner workings some tlc.

I'll look into those two latter things first and report back.....Sometime this year....Hopefully

breather?
manometer test and a Comp test like The V said

You've not bought them yet! I'm not attempting to have a go, and I've no idea whether they'd offer any benefit or not (although I'd guess that despite have loads of electrodes, you'd still only get one spark from each plug...), it just seems like a it of a strange idea to base a purchase on to me.

I suspect new rings will be cheaper than a yellow coil, btw.

Nothing personal but yes I understand and agree with Sean calling it foolish to buy all these silly gadgets, claiming to improve performance of engines etc. 2cv never had any of them in the past, I never fitted any fancy stuff and all my cars run straight standard with no problems whatsoever. The main issue is to understand mechanics and I’m not knocking anybody, if you don’t fully understand yes then it is easy to buy this shit. Don’t blame the seller, they are only happy to supply what people want.
So keep the bloody thing standard, do the right service and repairs, and do it to Citroëns specification and you’ll have little to worry about. Yes I’m a purist and it works.
OK grill me now

ha ha ha thats a bit strong! and not really what i was saying

the accel coil is better than the original, points assist and fully electronic have their place those plugs ive not tried(yet) but have done all the various different electrodes and "split fire" types in the past, still keep going back to the big box of cheapo NGK-use face discharge in one of the racers so we can volume the heads-they are a pig when cold.

BUT if you cant get it to go properly standard then you are unlikley to get it to run any better on all the possible performance mods, or rather if you fit performance mods you may negate any advantage by not setting them up properly.

the rubbishy stuff is clearly marked as so on the web shop, tho the descriptions seem to have calmed down a bit. shockers is a giggle tho'-clown shockers anyone

Sean
running :-points assist, resin 35000v coil( not accel) 9:1,slightly ported heads NGK plugs, diesel oil, bosh battery, lucas electronic V.reg, standard filter and exhaust, toyos, old Boge shocks standard height front -70mm rear, 150%(200??) uprated springs

happy as a sand boy

I like NGK B6HS or Eyquem C42S. After 21 years of 2cving, I've never had a problem with either. NGK always used to be my favourite, now on Eyquem. Can't tell the difference to be honest.

just give it a week

I always found Equiem to go off faster than NGK but your right if it starts and runs its not easy to tell which plugs are fitted

I fitted Eyquem plugs once....Never again. I have it on good authority that Citroen UK dealers removed Eyquem plugs and replaced them with NGKs before the cars were sold new.

Stick a cucumber up my a*** and call me a Dutch uncle if anyone genuinely notices any difference using these plugs.

Despite the description - which includes "The ignition spark always chooses the best path for reliable ignition according to the engine load." suggesting that only one electrode 'sparks' at any one time - I would imagine very strongly indeed that if there is any improvement, it could only be picked up in a lab using very, very sensitive equipment.

I think the 'theory' behind this plug is that there will always be one electrode out of the four which is in a 'better' position to fire depending on the swirl and movement of gases inside the cylinder, and that that electrode is therefore 'best placed' to do the igniting on that occasion. However, let's face it, all four electrodes are within a gnat's crochet of each other, so I really can't see it making any noticeable difference at all.

A spark is a spark is a spark. As long as the 'mix' is ignited fully and at the correct time, your 2CV will fly. The only difference I'd imagine there being between a 'good' spark plug and an or'nary one is longevity and reliability. Not better performance.
