Just wanted to tell you that you're not alone. Dealing with this exact issue as we speak. Mine was shipped about a month ago and now im trying to get it up and running and ran into the three valve vs four valve block issues. Im waiting to hear back but my immediate reply to their 2 day reply definitely slows this down. Good luck........ as it seems we both need it and many more may as well

Glad to hear I'm not alone on this but also discouraged it's happening at a frequency now. Let us know how you fare and I'll keep updating as well. Does yours have spring loaded idlers?
