Well, I will be driving to Columbia this year. The only thing holding me back is that three of my cylinder compressions are in the 50/80 range. Sounds like the leaks are mainly out the exhaust. I have new exhaust valves in my stock of parts and I hope the valve seats are okay. I will be pulling the cylinders off the engine this Friday. Franklin Engine Company doesn't have any stock of the parts that I MAY need (piston rings, cylinder liners, valve seats) and my main source of mechanical help (Gene Hamilton, Washougal, WA) is now premanently retired from the Franklin engine business.
Greg, Larry gave me your number last week as a possible source of help with the cylinder work - I will call you tomorrow and see what can be done. Yes, I keep my airplane at KKLS and Mike did my annual inspection ( I do the work and he inspects). If you are in the Vancouver/Longview area in the next few weeks, maybe we could meet for lunch (my treat) when you come out this way to visit .
I should have a better idea of what I need when I pull the cylinders.
Hoping for the best,
Allen (N1413B)
