Unless you have already taken on this before, this is what I would encourage you to try:
1) Change all four spark plugs
2) Change all the spark plug wires (buy the ones with silicone insulation...yes, expensive...

3) Buy a new distributor cap, and rotor.

4) . . . and the most important one, which is forever:
a) solid state switching instead of breaker points and condenser.

b) Pertronix high voltage spark coil (must have solid state switching)

Don't be surprised that your local auto supply store (e.g., NAPA) can get these MGB parts brought in over a few days.
