Title: Post war sparkplugs
Post by: 90plus on 07 Aug 2006 at 18:00
Hello,

I was wondering what type of spark plugs other members use for the following post war Douglas models?

Mark V ?

90 Plus ?


At the moment I am using the original Lodge spark plugs, but as they are beginning to become thin on the ground; I would like to change them for a modern equivalent.

Greetings,

Bert Ruys
