Get a generic 12 Volt coil that states "no external reistor required, for about $5.00 to $10.00 more than a resistor will cost you, and save yourself a lot of agravation! The problem with using a resistor is that not all coils draw the same current, so a certain value converting resistor that works well on on type of coil may be too low in value for use with another coil, causing rapid point wear, and an overheated coil, or with another coil the value may be too high, causing weak spark. If you insist on a converting resistor, a "real" auto parts store should be able to come up with one to try. When you get it running, check for 5 to 7 Volts on the resistor (switch) side of the coil.

Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
