so I started pulling apart the motor today because it needs to be cleaned up and I wasn't going to bother doing a rebuild and low and behold this is what I found....so the previous owner obviously didn't take care of this thing.
it's completely full of sludge it's wonder the thing even ran.
I would clean that out really good, and I bet the tops of the cylinder heads/rocker arm area is nasty too. Most importantly, though, don't let that stuff fall further into the engine! Then I would change the oil after the first few times of driving the thing.
And this is why builds should be done in manageable phases kids.
