Okay so I picked up this little motor from a family member. I started it in a barrel and it ran fine. What I DIDN'T know was this was a dual air/water cooled engine. It started smelling really hot and at about the same time I went to shut her down, it shut off on its own. Let it cool all night and would not start this morning. I just did a compression test and only got 30 lb of pressure, and it built really slowly, taking about 6 pulls to get it to 30. I am new to all of this so bare with me here. Is that a signs of bad rings? I have good spark and fuel. What kind of project am I looking at to replace the rings and probably the piston? Would it be better just to grab another motor on craigslist to avoid a huge hassle? On another topic, once I found out that it has a waterpump and impeller, I pulled off the lower unit and attempted to remove the waterpump housing. The screws are so old and crusted over that I don't think there is anyway to get them out. Any of you experienced guys have a trick for this? I am stuck on this. This boat/motor was my grandfathers so I would like to keep it around so that's the only reason I am even considering it. Much thanks.
