Just to let you know, I've never taken apart an engine before. so for me, this is a big learning and exploring process!

so, I got off the head, the cylinder,and the piston head (HC&P). Remember, the problem was that as I rotated the engine, I would hit a spot of greater resistance, and then it would rotate easy once through the "friction zone".

With the HC&P off, I rotated the engine again. Hmmmmmm, same "friction zone". Looking at the the connecting rod as I rotate the engine (after I fished out the timing chain), the friction came as the connecting rod (CR) was coming out (kind of like when you stick out your tongue). So what I did was spray some WD40 right at the point where the CR is attached to the crankshaft.

Wow, BIG difference! No friction!

Now, before you ask, the engine oil level is full, according to the screw in plug. But there is ONE more interesting thing (for me).

When I rotate the engine, sometimes the cams on the crankshaft get a coating of oil on them, but sometimes not. When it does get oil on it, it only covers about half of the bottom of the cams.

Well, what do you think???
