Cal Flannery, 717 Platinum Rebuild sent September. One respopnse from Dan: "Ok, I'm just short on office help right now". Lauri had advised rebuild - Feb, Mar, Apr. Engine had debris in crankcase that damaged rotating valve / manifold. Pics of damage determined workable. Sent engine with magneto assembly attached, couldn't get it off. Dan took the time to respond but no follow up. Very much appreciate any help.
