from ignition switch red wire supplies power from the battery to the ignition switch, black wires are live when the switch is on but have nothing to do with the cdi The cdi is supplied by the generator on your engine.Green wires from switch are all earthing wires.The black and white wire coming from the switch is the wire that puts the cdi to earth to disable the ignition in the off position .
Could be a variety of things. Vapor lock from a leaky carb. Carb running too rich. Engine overheated. Heck, could even be some weird wiring gremlin. Hard to tell for sure, but a good solid carb clean and reset should help either way...
Hi, Ramacae the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or a damaged battery, 9 volts or lower.
2. Faulty alternator/generator and or voltage regulator.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, O2, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Water or dirt in the fuel system, carburetor or filter.
9. . Restricted, blocked or kinked fuel line.
10. Fuel tank empty.
11. The gas cap is not venting properly or fuel tank venting system blocked.
12. A faulty Fuel Pump, pressure regulator and or fuel injectors.
13. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
14. Needle and seat stuck closed in the float bowl.

I am not sure if the 81 has points or not, if it has points thats the next check. If it is a cdi you will need to check the gap of the rotor then any wires going in out of the cdi unit. Next would be that the cdi is bad.
Obviously the CDI is picking up power from the starter button. Check the ignition key switch for proper operation. Chances are that whatever fried the loom also fried part of the switch. Alternate to that, trace the wire powering the CDI system, disconnect it at the source (starter button connection), then find a power source that is live only when the key is turned on and then hook the CDI wire up there.
