I am considering installing electronic ignition in my Massey Ferguson 175 Perkins gas tractor. Several years ago I replaced the points, condenser, and distributor cap/rotor. Had trouble getting the distributor turned to the correct position to set points due to the high compression of this engine, and the starter lockout when the transmission is in gear. The distributor is also a real pain to access since it is behind the loader frame and arm. Think I had to remove all the spark plugs last time to allow setting point gap. It is mis-firing occasionally now and likely needs more ignition work. Are the electronic ignition kits all the same, or do I need a custom one for the distributor on this tractor?
