Thanks for your reply but I don't get any spark at all...so any test of this sort is out of the question at this point.

Early-model Boyers are sensitive to voltage drops, so make sure your battery and charging system are in good shape.
 
Double check the wiring to the coils is correct, with the coils wired in series and the ballast resistor is by passed or removed.

Wet with fuel to be precise.

So could the fueling. Be way to rich leading to quickly fouling plugs and shut down?

Have you renewed and checked the float bowl needle seating such that you know they are closing off fuel as float rises to the spec"d height in bowl?

Or are you saying no spark when testing clean plugs removed from head and grounded to engine? That would be electrical of course.

^^^ this, and IF you use a battery tender and you have a charging/battery problem, the battery tender masks the problem in some scenarios.

You plug the bike in and it charges the battery. You unplug the bike and it starts right up, making you think everything is working fine. Later on as you ride and your voltage drops, the spark becomes so weak that your plugs foul and you swear it's a carburation issue. You plug the bike back in when you get home and start the confusing scenario over again. If the battery gets very low, then you get no spark at all and you're back to thinking it's an electrical problem... been there...
