No Compression in 2 Cylinders
Good Morning! ... my name is Keith and Im a newbie here, I just purchased a 1973 Catalina 27 for $1500 in San Pedro CA. The boat seems to be in decent shape except of course for the engine. The boat motor spins freely while attempting to start it and I can hear it firing and almost turning over. A compression test found that the front and rear cylinders have no compression.
I have briefly read up on the atomic 4 and from what I have seen, the valve springs are weak and can get stuck.... so my kneejerk reaction is to spray some Kano Kroil into the cylinder heads and let things sit in hopes that the valves free up. Is this the first course of action one attempts in this instance and is there another thread with an SOP for this? My motor is super tightly squeezed into the Catalina 27 engine compartment so Im not sure I can easily access the valve cover without pulling the motor ... thoughts on this as well?
Thank You in Advance
Keith
