Have you tried adjusting the gap (throw) of the points. They wear,
and sometimes need readjusting. The manual for your car should tell
about this (my MGA manual did).

When I had my MGB, it had an after-market electric pump installed in
place of the standard SU pump. The new pump was connected to the old
plumbing with black rubber hose, which managed to spring a leak every
couple of weeks. I got quite adept at reaching under the car, slicing
off the unwanted hole, and reconnecting the hose without smelling like
a gas pump.
If you go this route, figure out some way to use metal piping, or at
least get some high preassure rubber hose.
