Thanks for the reply
I just bought it and the guy said it did not run so I pulled the plug wire off the plug and put a plug in it and laid it on the head and turned it over and got no spark. Whats next ??? Thank You

if your starting it w/ the switch and not the pull rope chances are the kill switch is working ok. the coil might be bad or it can be in the stator behind the fly wheel.

Can someone tell me how to test these parts to track down the problem. Thanks

I'd suggest getting the Clymer or Haynes manual. They will walk you through a step by step process of anything you can check without dealer tools. I prefer the Clymer manual but they don't sell it for every model. I believe only Haynes makes a manual specific for your '90 Trailboss.
