Hi, Guys. I have a 14.5 HP Briggs OHV single cylinder on a riding mower. It currently runs somewhat rough as it spits through the intake and occasionally backfires. Is this most likely the valves not seating correctly? Should I lap the valves? If so, what grit should I use? I adjusted the valve clearances and no change. Thanks for your advice.
