Our 2588 crapped on us yesterday.
Missing and backfiring out the aircleaner. Engine has 700hours. Dad looked at it and it looks like a valve is not opening or something. I personally haven't had a chance to look at it. Our dealers seem to know little about the NEW engine. One service tech did mention an update with something to do with the lifters(pin?). Has anyone else had or heard of problems in this engine? Glad were almost done,can finish with the 1688.Thanks for any info.
