Unit starts and runs great, no performance problems, Idles great. Until it gets warmed up then if you shut it off it will not restart for 15 to 20 mins. After that time it will fire right up and run great like nothing is wrong. Never faulters, always idles good, never dies, only acts up if you shut it off when warmed up. 6200 miles on unit, has been acting up for the last 1000 or so. Has not gotten any worse over time or miles.
