I would expect that since you only got a blue spark from the coil wire to ground that your primary ignition circuit is in trouble. You filled the points but you must regap them when you do that. While you have the distributor open, get the points closed and then push radially on the distributor shaft while watching the points. there should be no motion in the points and the allowable runout on the shaft/bushing is like 0.002". If you see motion at the points your distributor needs a re-bush. If you have a voltmeter measure the voltage at each node inthe primary circuit from the battery to tthe coil and to the distributor. You should see battery voltage from both side of the key switch(key ON and points closed)to the battery side of the coil, UNLESS you have a resistor in the circuit. You should see a very small, but not zero volts on the distributor side of the coil. Make sure that the sign on the distributor side connection of the coil is the same as the Battery ground. If the battery is positively grounded then the wire to the distributor from the coil should come off the positive terminal. When you find and fix the problem and check the sparkusing the coil wire you should have a FAT, BLUISH WHITE SPARK.

Picking Corn - by Rick Nikolich. It was the day before Christmas shutdown at work and I asked our lead engineering expert Scott Andrzejewski what he was going to do over the holidays.

He wanted to get the rest of his corn in by the next day (Christmas Eve). We had about an inch of new snow on the ground and single digit temperatures. So in the bac
