I am in the process of rebuilding the 14hp Kohler engine on my 1977 Power King. Although I've had this tractor for almost 15 years, I made the mistake of letting it get low on oil (yes, I know better!), and when it started making noise I shut it down, added oil and I restarted it. But very quickly afterward it started knocking very bad and before I could shut it down again it died. It still turns over when I crank it, but will not run. From the thumb test over the spark plug hole I don't feel any compression, but based on the Kohler manual, as these engines have automatic compression release, I'm not sure you can check for compression that way. So I guess it's time to open it up and see what happened. As having never done an engine rebuild before, if anyone has any advice to give, I would appreciate it. For me, the easy part is done - I have the engine out. As I have little experience disassembling and re-assembling engines, now the hard part starts. Thanks in advance to anyone who has any advice.
