I replaced the (front mount) coil on my '47 earlier a few weeks ago because it was beginning to fail. The tractor ran better the next two times I used it, but would not start for the third planned mowing session. I replaced the points and condenser but discovered that the distributor cam was so worn the maximum point gap was .009". Assuming my new coil was okay, I bought the basic Pertronix EI kit from a local (Columbia, MO) dealer which doesn't utilize a regular automotive type coil. I was stunned to discover how bad these Taiwanese aftermarket coils are - the old aftermarket coil lasted eight years, but I didn't get eight HOURS out of the latest one. Then I bit the bullet and bought the Pertronix kit from YTC that I should have purchased the first time. I installed a 12v conversion kit in 2006 and there was just enough room on the top alternator bracket to mount the coil with a 1" carriage bolt at about a ten degree upward angle. The tractor started on the first crank and was running stronger than it had for a while. The worn point cam was surely having an effect before the ignition stopped sparking. One nit-pick with the kit - the adaptor plate sealed the distributor cap cavity, but left a small gap on the side of the distributor opposite the mounting screw. If the screw supplied to help hold the adaptor plate to the distributor was a tad longer, the cork coil gasket could be used to seal the distributor better. I don't think it will be a factor in performance reliability because the EI sensor is sealed and should not be affected by a little dust or moisture. This is easily remedied with a squirt of silicone or a longer screw and reinstalling the coil gasket. Anyway, I'm happy to have the tractor up & running again!

Today's Featured Article - On the Road with Dave Gohl: Tractors and Farming - by Dave Gohl. I never thought I'd live to see the day, when I could call myself a farmer. What allows me to say this? Well, when our family moved to our 20 acre site near New Prague, Minnesota, I had one thought in mind. You guessed it, farm it somehow. A little history is in order. In my younger days, mom, dad and my brother made frequent visits to dad's youngest brother Pete, who took over the home farm from grandpa MIke. It was the typical set-up, milk cows, pigs & chickens. In the winter, we'd play
