GAHHHH!!!

Smashing the pin from the Lucas dizzy is a nightmare!!! So tempted to drill it out and find a replacement pin.

Did anyone have a tacho installed with the pulsar dizzy?

Before I had the sender for the tacho on the -ve side of the coil but now it does not seem to work with the same configuration. Took the volt meter out and placed it across the +ve and -ve terminals of the coil and found I got different readings from the old dizzy setup. Old one pulsated on and off reaching 12v, now I read a constant 3v.

I've not done a voltage test on there but most tachos work OK with a Pulsar dizzy, including Smiths.
4myego just fitted a new Smiths tacho in his, it's working fine.
I run a Veglia Borletti (ex Fiat) it works fine too.
I had an early Smiths one in the wife's S replica, it worked fine but read high on hot days (old tacho problem).
All these cars running Pulsar dizzy.

<edit> If I recall correctly from past threads, some cheapo tachos do need a diode in the sensor wire to work properly with electronic ignition.

Hmmm, I have a cheapo tacho from ebay
http://cgi.ebay.com.au/MARS-2-5-INCH-60 ... 286.c0.m14

Might have to invest more in a better one then :(
I'll try putting a diode on the signal wire first to see how that goes.

Thanks guys

Hi guys, i bought a couple of these dizzys from the wreckers and built one good one out the the three, modded the plate etc and lubed it all up. Fitted on the engine like a glove and tunes up like a beauty. Wow what a difference it has made to the engine. Cold start now is like a 2009 EFI car, no missing or carry on. Very pleased!

I do notice the engine still pings a tiny bit here and there under ceratin loads at around 3500rpm but i am sure this is related to the carby tuning as it is not setup correctly.

:D

It could be the same, I believe the body size was standard on most Nissans.

I have recently acquired a 1979-82 Honda Civic one, these do need a bit more modding to fit but they work OK too.

I know there is also a Subaru one that works, a member here has one in his Moke, but I've not eyeballed it to ID what Suby model it's off.

Note on reassembly of Pulsar dizzy:
The star is fitted with the numbers on top. It won't spark properly otherwise.
Spark occurs when the steep side of the star leaves the polepieces.

I'm gonna try to source a pulsar dizzy this weekend, I reckon I'll get one for my mini cos I'm not that keen on playing with advance curves on my supercharged morris 1100S, detonation + boost = sadness.
if I can get one into my mini easily and cheaply enough ill try one on my 1100 though.

BUMP.

Mine is a d4r83-39 too, if the 39 is the advance that's not ideal at all.

Also with spark plugs the higher the number the colder the plug. I usually run 2 units colder in the 205.

I believe the `39' or whatever number is the vac can spec, I leave them disconnected (most have a blown diaphragm anyway).
They are just an economy device for low performance engines... :P

Not quite true, completely up to brand i.e. NGK the higher number is Colder but with Bosch the higher number is hotter.

Ahh right, I only ever use ngk (jap cars is what I work on 99% of the time), learn something new every day.
EDIT: I had a blonde moment today when playing around with the pulsar dizzy.
