RE: Looking for parts
I don't use the magnums myself but most of the guys at the field that started out with them have a bunch under the bench and use them for parts engines. If you belong to a club just ask around. I'm sure someone will have a carb. Like Jester says, if you find one that fits it will probably work. The OS home page is the other good idea, I would go there and ask. I don't have any parts for the 60s at all any longer. One of my LHS {local hobby shops} has a big box of old engines and parts, if you have any real hobby shops in your area most of them have the same thing. Chain stores usually just sell new stuff. Hobby People is the distributor for magnum but when they wear out or break most people just toss them, sort of like the OS LA series, they don't cost enough to worry over. The OS are another story and well worth fixing or rebuilding in most cases. Maybe look on the main glow engine forum.
