I'm glad to know about you again and happy that your sanglas, still on the road.
Maybe next time you came back would possible to have a meet.
In other hand, do you know the new electrenic ignition system?, a spanish company called levistronic had developed. With it, your sanglas would be like a modern bike, easy to start and provide a better engine performance, take a look to their website.
Also, we had tested with modern keihin carburators to replace the current amal and works great.
