Hi Old Magnet. The Eisemann service manual page you show gives the magneto that is recommended to replace the original mag on the Twenty Five. The parts book shows the GV as what the Twenty Five came with.
Thanks. Ken

My CAT 25 has the GV4 as original. Early CAT 25's may have come with an earlier Eisemann magneto as they were converted late CAT 20 tractors. Bill

The GV was also used on the late PL Twenties. I can not remember the serial number break for the change from the G4 Eisemann to the GV. I am thinking of putting my extra oil filter assembly on my Twenty Five.

Anybody know what spark plug was used from the factory for the Twenty Five?
