Nice Atlas Westie,
I can help you with your mag if you like, I am in Concord Twp. Ohio (about 30 miles east of Cleveland). I am the largest USA distributor & installer of the Brightspark Easycap magneto condensers. For about $20 you can replace the capacitor, which is the most common mag problem. Keep in mind, the original Lucas capacitors were of poor quality & only had a 10 year shelf life when new!!! The armature could be bad, but not as common & fairly expensive, by the time you get it rewound & pay shipping & insurance it can be around $200. The bearings often just need cleaned & re-greased, but are not difficult to replace with the correct tool to remove the races. There are a number of other faults that can occur, but the capacitor is by far the most common problem. I highly recommend going to the website & see what you think, sounds like you could do it yourself & if you get in a jamb I am happy to give free technical advice. In addition to doing all manor of Lucas Magneto rebuilding & repair I own an original vintage Bosch magneto remagnetizer to re-charge the old magnets in the magneto. If you choose not to do your own work, I am happy to do it for you, estimates & inspections are always free.
My thoughts on magnetos:
electronic conversions work well, but when they fail (yes, they do fail also) they fail 100% no spark at all, mags tend to go bad a little bit over time, or only go bad when hot.
Joe Hunt makes an awesome mag, works a treat. Looks good on a race bike, looks silly on a vintage restored bike (IMHO). Oh, & bring about $700 (including S&H, insurance) to the store to buy one.
Lucas mags, when set up correctly, work for many trouble free years if cared for & maintained according to the manual (provided it has had the Lucas capacitor replaced with a Brightspark Easycap of course
)
