I've been trying to put my '40 H back to its original magneto ignition. It has a perfectly fine, functional coil and distributor on it, but, I really like magnetos better. No good reason, just preference. I've disassembled my H4 mag and cleaned all components. The tractor has run on that mag, but it seemed hard to start, so I thought a thorough cleaning was a good start before I started replacing parts. Its all nice and clean, the coil, although old, appears to be in fairly decent shape, as did the points and condensor. It will throw a spark across an air gap of .066, but no more. The spark is "thready" and sometimes has a small tint of yellow. Its not a nice fat blue spark like I'd like, but I've been told that if it will cross that large of a gap, it ought to run fine. The tractor is hard to start on the mag, but once started, seems to run fine, even after warming up. The timing is set per the IT manual, points just sparking on #1 TDC, and the plugs and wires are all in good shape. (both new, and properly gapped.) The engine is topnotch, w/ new valves, guides, seats, pistons, sleeves, rings etc. It has excellent compression, and, as I said, starts easily and runs great on the dist/coil setup. I'm guessing a new condensor is in order, hence the occassional yellowish spark. New points can't hurt. I may even cough up enough for a new coil. If I replace all of those, should that cure my problem? How about the magnetic rotor? No one around here seems to have the stuff to "recharge" it, and that is pretty much the ONLY thing that would be left to do. It doesn't drag in the fields anywhere, (did a prussian blue test to ck) Any advice is welcomed....

He farms around a hundred and fifty acres of arable land, in a village called Southam, located just outside Leamington Spa in Warwickshire. The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
