Thanks for the reply - perhaps first of many! Yes, forgot to list the replacement of the points. Yes, have definitely checked for spark by having some one turn the key (in this case) while I check for spark. I've repeated the experiment four times with consistent results = warm engine, shut it off, no spark - wait 30 min. fires right up no problem. But the dwell does increase - then I reset it and sure enough after a while it increases again. Have not taken a voltage reading on the primary side of the coil - will do so tomorrow morning. Assume it should it be 6v. since this is a six volt system. ???
