If you are having ignition or starting issues or poor running conditions with your Vanguard-powered tractor good chances it’s the coil system. If 1 cylinder seems weaker, skips, off time, cooler, hotter you may have an issue with your coil system.  Some other indicators of an issue could be if you notice some black smoke, backfires, fouling spark plugs, less power, or runs more erratic with the mower deck or blower turned on.  Also, if your machine won't start, won’t shut off right away, etc these are just some possible symptoms indicating your issue could be coming from the coil system. 
 
The diode wire is very important and should be replaced when coils are and we always recommend replacing coils in pairs. This is a pretty simple job but the motor has to come out to do it. The good news is the Briggs Ingersoll’s engine can be completely out in around an hour for most.

We highly recommend replacing your key switch at this time.  The key switch and the wire from it going to the coil diode shut-down wire are the only parts left in your ignition system to replace along with two new spark plugs.
