I have a Gale made 12hp Sea King. Model gg8971a. What should compression be on this? It’s been sitting since 1980. I’m getting around 60 on each cylinder. Thanx in advance ,Mike.
I agree Frank. It runs great in a barrel but sucks on the ramp. I can leave it on the trailer at barrel height in the water and get it to run good. What about de-carbon if process? Most are done on a hose but can’t do it with this lower unit. Any ideas?
