With a restoration of a 1972 TR6 just begun, I come across a problem ( one of many) that I can't isolate yet. It will run decently for a while then begin to misfire so badly that it is difficult to get it going more than 25 mph. An then...... It will run fine again. The usual have been done. New points, plugs, plug wires, coil and condenser. It has been timed and the carbs have been adjusted, not rebuilt yet but adjusted. The odd thing is that when it starts to misfire, I found that if the engine is turned off and on again the misfire will often stop immediately. Not every time but most times.
any ideas of the cause?
