I have a Swisher zero turn with a 27h.p B&S ELS engine. It has 20 hours on it and started making a popping or backfiring noise at half to full throttle. But, it doesn't seem to do it while under load.(at least I can't hear it then!) Any suggestions? Thanks

With only 20 hours on it, I'd be looking into warranty service. It could be as simple as a spark plug, but it also could be a valve problem or camshaft problem.
