Good afternoon All

Does anyone know the correct distributor points gap and spark plug gap for a 1995 Mazda B2600 4x4 double cab (petrol motor without fuel injection)?

I’ve had four breakdowns in the last year, the symptoms are rough running, loss of power, backfiring, and eventually no spark. I’ve spent thousands on repairs by a mechanic (and towing fees) but the problem keeps coming back. The car runs normally for a while (usually less than 100 km) then develops the same symptoms.

The mechanic has changed the points and condenser (multiple times) and then the ignition coil (not the ballast resistor). On the advice of an electrician, I’ve replaced the plugs, points, condenser, rotor, and distributor cap. The electrician said the ballast resistor is fine. The motor’s running but still rough. The Mazda B-series owner’s handbook that came with the vehicle when I bought it (2nd hand) has figures for the points gap and plug gap for all models EXCEPT the B2600.

Thank-you.
