I've had my 460 International Hi Utility 90% disassembled for over 2 years (yes, I'm slow). Finally got it together enough to try to start it. New wiring harness, old coil, but I have tried more than one. All worked when removed. Currently have installed a working 12 volt coil from my M that uses an external resistor (says so on the coil). I get no spark when the coil wire is pulled from the distributer. Wiring is exactly the same as in my owners manual. Wire from starter button to resistor. Wire from other end of resistor to + coil terminal, along with a wire from the R solenoid terminal to the + coil terminal. Negative coil terminal goes to distributer. I get a good spark from the wire that runs from the R terminal on the solenoid to the + side of the coil, but only a small spark from the wire running from the (-) coil post to the distributer, and absolutely no current, according to my bare fingers, coming out of the coil wire. Tractor is factory 12 volt, negative ground. Have tried 3 coils, current one with and without the resistor -- I'm lost, as usual. Any suggestions are appreciated.

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.

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.
