well that was interesting:
Can of Carb cleaner, then wd-40 and some grease all was good and some silicone .
did a leak down test... Cold 5 were leaking 3-4%, 1- 8%, 1-10%, 1-16%
ran it this morning after fixing the starter. the one leaking 16% went to 4%, the 10% dropped to 3%. All is good.
ran the valves.... adjusted 3 out of 16. Not bad after better than 140 miles worth of river time.
