I just got slightly used Little Wonder edger with a Honda 4 H.P. You can tell by looking at the machine that its only been used a handful of times. It barely started and was flooded with oil really bad so I cleaned out the cylander and changed the plug. It now cold starts and runs like crap. I noticed someone was into the valves because the valve cover bolts had noticable marks from sockets. I don't have the specs but I popped cover and the seemed to tight so I backed them off about 1/8 turn and now it starts much better but not after its warmed and it still sounds like a damn Harley. I've never even seen a Honda run that crappy. I still think its valvetrain though. Some please help with your opinion.
