Went to start on muffs and cranked over after 2 turns and started. Little rough, hunting for idle but have a check engine light and the one directly underneath it on (smartcraft sc1000 gauge). No bells/buzzers. Doesn't seem to run any different, rev'ed up to ~1200-1500 only. Temp stayed in normal, tell tale stream was strong, turned on/off 4-5 times and check engine light comes on after about 5 sec. I'm stumped where to start......ran beautiful when put away last year......

Check all cylinders firing..(plugs,leads have spark)..Sometimes its as easy as a loose plug.
