Bluenwhite, thanks. This is an original truck, with most everything original to this truck so it does have oil bath filter, 12-volt system, + wire to coil from starter solenoid. Since this problem developed, it has a new fuel pump, points, plugs, condensor and coil ... at the rate I'm going it's not going to be that original for long! Will try your tips, along with the others I have gotten here until I get it going. Thanks to all for the suggestions.
