That makes sense, thank you! He only put about 12,000 miles on since he had it, so they‘ll be okay… Anything these need in the way of tune-ups besides spark plugs? I was thinking about things like valve adjustments, but I heard these don‘t need valve adjustments? Or am I wrong on that? Thank you all for your help, I‘m trying to figure out what these gas engines require… I‘m also going to try to get my hands on some sort of service manual…
