Well as some of you may know a bought a Bush Hog D4-7 a while back. It had not run for a few years and was sitting on flat tires. I still work 8 to 5 and that dosen't leave me a lot of time to tinker with it. Now that the weather has turned nice my first thing to do was to get the tires tubed up to make it mobile. That went pretty well as the wheels were not to rusty. So I now played with it a bit to see if I could make it fire up. The spark seemed to be very weak and intermittent even after cleaning up the points. With the ignition system being under the flywheel It would require some major disassembly that I was really was not wanting to get into just yet. So today at work I rooted around for an old 12V coil and a condenser, found a coil wire and made up some basic wiring just to test with. So I disconnect the old mag Ignition from the points and hook up the neg side of my coil in that location. Then hooked up my power and ground to the battery. I then removed the spark plug and attached it to the coil wire and checked for spark when I cranked the engine. BAM ! That thing was zapping like lighting bolts. It was sparking so well I increased the plug gap a little just for the heck of it. I then shot a little chem tool carb cleaner in the cylinder and screwed in the plug. I also gave the carb a little shot as well. Hit the starter button and in about three revolutions it lit right off and sounded pretty good. It seemed like it ran quite well as long as I kept spraying it. I was a happy guy. I then wondered if it would take fuel and run on its own so I checked the tank and it was quite clean and dry so I poured in a couple quarts of fuel and opened the shutoff valve. I then gave it another shot to light it off and it fired right up and sat there and idled like a champ. OK, well now we got to take it for a ride. So I hopped on that bad boy and cruised up and down the street a few times. Seems all the gears work, the clutch feels pretty good and it has some brakes. I guess it wasn't to bad of a buy after all. I will let you all know as this continues. Sorry for the lack of pics and the post being a bit long winded.
