« Last post by eddie on Yesterday at 18:49 »Check out the magneto. With the points cover removed, see if the points plate can be lifted (even if only a few thou). If it can, then the armature bearing is probably loose in the end plate, causing one cylinder to run retarded of the other. With the end plate removed, you will find the bearing is smaller than it's housing - this is intentional as the bearing should be in a paper cage to prevent the armature from earthing out through the bearing tracks, causing them to etch away prematurely. When replacing the paper cage, a light smear of 24 hour Araldite on the cage, between the bearing and it's housing helps to provide extra support for the bearing. (Obviously, leave the magneto for 24 hours before using it - to allow the Araldite to fully cure).
