Re: How bad do my pistons look?

Yes, do the whole top of the engine and while you are at it, clean up your studs with a flick of the wrist.

The piston rings wear thin --especially in long stroke engines and start to rattle up and down in the groove. After a while they break from flexing in trying to seal up a heavily tapered cylinder The individual pieces really rattle in the groove and sometime wear a path right up through the top of the piston. Chances are your lands on #2 are already toast.

See if you can borrow some tools to measure your bores top and bottom.
