Why does my truck run like the timing is off ? The points were sticking and I

vacuum pump up and down. Thanks

In the long run which has already been a long run since 1969 best bet is too buy a Ignition Conversion Kit. New plug wires and spark plugs and cap ect.

Vacuum advance may be at fault or low vacuum to begin with.
