Forgot to say that the weak spark might be caused by a bad
condenser.
THe condenser helps keep the spark from occurring across the points
instead of at the spark plug

I've got no familiarity with what a condenser is (outside of HVAC)
in car circuitry. But thanks for saying what it does.

The green lines are energy stored as magnetic field in the coil, the
black ones are energy stored as electric charge in the capacitor. The
oscillating transfer of energy between them is similar to a swinging
pendulum that swaps its energy between speed in the middle and height
at the ends.
