Accuspark

[elgreco]

Has anyone installed accuspark or similar electronic ignition? If so, are you happy with it? I have ordered a kit on a whim and am awaiting its arrival. My MG is running quite well but I was impressed by the blurb about improved performance and fuel savings. It was only about 29 pounds so not the end of the world if its rubbish.
Thanks for any feedback

I still use points on my MGB - and I have never really had a lot of trouble with them if they're replaced and gapped correctly.

*However* I have had a lot of grief recently with what turned out to be a duff rotor arm - there's a lot of this about at the moment it seems - car runs for 20 minutes or so then packs up and won't restart until it cools down.

Turns out that the worst offenders have a rivit holding the copper blade in place and are black (too much carbon in the plastic) and when they get a bit old and/or hot they break down.

Look absolutely perfect to the naked eye but they short out when hot.

Made worse when people upgrade to electronic ignition and powerful coils because the voltage goes up and they brake down more easilly.

I'd deffinately recommend having a spare rotor arm in the glove compartment and check to make sure there's no rivit in it and that it's red rather than black.

After the fact I found out about it here:

available here too

actually there are black ones on that page too with a screw or rivit they look like the type to avoid!

On all my early vehicles i ran 'lumenition optronic' electronic ignition, superb product we used them on all our competition vehicle. What always impressed me was when you put a timing/strobe light on the timing marks with points it fluctuated all over the place with electronic ignition it was rock solid.As soon as i purchased a vehicle with points i fitted electonic, so easy to fit.

I got one a long time ago for my 1965 jaguar s-type, the only advantage was not having to keep cleaning and adjusting or renewing the points, never failed in the ten years I had it.

Thanks to you all for your replies. Most helpful. I think I am only doing it for a 'belt and braces' thing. I am glad that no-one has said that it is a complete waste of time. Awaiting delivery now and then will let you know how it goes.
I WILL keep the old system in the glove box with the spare rotor arm, capacitor, points and plugs. Thanks again.

never had one fail but i also kept all the old bits just in case....
