A universal coil will not work. A 1976 JAWA should have the 207 engine. Coils are not the easiest to come by but if you're handy with a multi-meter, then head out to a junyard and start testing coils to find one with the correct secs. The most important thing is that the primary winding of the coil be of 1 ohm or less resistance as the thyristor ignition uses the coil as a ground. The secondary side should be around 6k. I've been working on my time machine made from JAWA ignition parts, and should soon be able to send coils and chain covers back in time. Oh, and BTW, enjoy your summer now, in about 3 months things are gonna get real fucked up!
