OK, I am almost done with the restoration of my 1925 Fordson F that has an English made Model N engine. It has the impulse magneto conversion up front. I have the magneto manual, and both F & N operators manuals, and I still cant figure out how to do the engine timing. Right now the entire radiator has not been re-installed, so there is plenty of room. Cylinder 1 is now in the full up position. I am supposed to line up the magneto plate with the arrow in the up position, but there is no arrow on/in my magneto. Does the non existent arrow correspond to the rotor location, and, how do I access the timing gear, can I just remove the front timing cover, or is there a view hole somewhere that I don't know about. Any help would be much appreciated. Thanks, Larry.

Hi Larry,
Putt your finger in spark plug hole first cylinder. .....turning engine with your other hand. ......When compression will go out (explosion )the spark must come on spark plug beside. .....iff not. ....take off magneto. ...turn magneto half turn. ....putt on again and test. .......Do that. ....you will get it working :wink:

Vasalle, thanks for the info. Sounds pretty basic, so I may actually get it right. I am used to things being a tad more complex with the later Ford tractors. Thanks again, I will do as suggested, Larry
