CJ is a standard plug usually used with points
RJ is a resistor plug usually used with Hall effect magneto triggers and a plain cap

The rj12c is a slightly different heat range than the cj14. It is a slightly colder plug plus resistor.

Well if someone had look-up the mower along the serial number they would have found the you had a CDI ignition coil; therefore, you would use the RJ12C non projected spark plug. Luckily the 1993-1995 LB-10515 all use the CDI coil.
