Subject: Re: magneto for 2 litre
Hi Folks,

I eould like to add to this debate. I use an ML magneto on my 2 Litre and I like it very much. I also like Scintilla magnetos, and some years ago bought a Scintilla GN4 for my 2 Litre. In my opinion the GN4 is a large lump more suited to a commercial vehicle rather than the 2 Litre and I have just sold it on eBay - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=330328442857 .

By the way if you don't know, "G" stands for Grande - ie large. It is and I don't think Lagonda recommended a "G" Scintilla on any car. 16/80s used a PN6 (P=petite), and my M45 has an MN6 which is half way between the two. 3 Litres use them as well - running at 2/3 engine speed not 3/4.

Scintilla PN and MN magentos are very expensive to buy now and before I bought it, my 16/80 was robbed of its PN6 and an 6 cylinder ML put in its place. Actiualy I don't mind because ML magnetos are easy to work on. One important feature is that there is a chamber where a standard capacitor can be put - they do go faulty. Also the coil is easy to remove and can be re-wound quite cheaply.

I would strongly discourage anyone with a 2 Litre from using a BTH rotating coil magneto (of the type used on a Rapier) - certainly without having it re-wound. This is because the coil on the armature was originally impregnanted with shellac and when older magnetos get hot the shellac runs out and causes it to seize. This will result in your fibre timing gear being stripped and the car being immobile.

Keep sparking folks
