My father gave me a Stanley garden tractor with a 21hp Briggs V twin OHV engine, i think it is the Intek. I don't have the model number with me, i'm out of town at work. He says it's running on one cylinder, it definitely has a lot less power. I'm a newbie to small engines, but i do know there is some spark to both plugs, and the compression is 120 on one cylinder, 140 on the other. I have not determined which cylinder is not running. Can some of the experts here give me a list of things that could be the problem, and how to check them? Like could it be the coil, etc?
