Pretty sure I do - pull the plug, make sure the plug wire is connected and ground the outside of the plug against something, push the starter button and look for the spark.
Any other ideas? One of the other guys at work suggested that fuel injector cleaner idea too. I might see about getting some of that stuff too. I'm not too fond of adding a lot of stuff into the tank, but other than checking for no spark, I really don't know what else to check for.
Maybe, after all the "trying" to start that I have done, my plugs are fouled. I'm wearing out a raw spot on my head from scratching it!!
