1969 Ford f100 starts but runs Really rough
Why does my truck run like the timing is off ? The points were sticking and I
manually gapped them and it runs like the timing is off unless I yank on the
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.
Check for vacuum leaks.
These older models may use vacuum pump for wipers, dist too.
