It uses propane, not gasoline. At first it worked great. We started it and ran it for 15-30 minutes a couple times over the winter and everything seemed OK until last week when we were getting it ready to go camping. Now it starts but stops immediately. The air filter looks brand new and the exhaust pipe is not obstructed. We want to change the spark plug, and know where it is located, but we can't get it out. Is there some kind of special tool for removing the spark plug? Or maybe is it metric? Any suggestions would be great. Thanks
