When I try to start it the unit will run for 5 seconds or so before cutting off. I've replaced the sparkplug and air filter and put in new gas (I forgot to drain the tank this winter).
What should I do next? I'm not too familiar with these engines. I called around for a repair place, the only place I found who would touch them was Sears (the downside of living in a small town). None of the small engine repair shops do anything besides mowers.
