Sorry, Mike.<br /><br />Distributing copies of copyrighted material is illegal. Don't ask.<br /><br />Go to the library. Oddly enough it is legal to make copies from a library copy. Might cost you a dime.<br /><br />Good luck. :)

Mike.... Remove the spark plugs. Disconnect the large red electrical connector at the engine. Rig up some kind of spark tester. Crank the engine by jumping the starter solenoid and observe for spark.<br /><br />If you now have spark, the usual cause is a shorted ignition switch.
