Well, I found I had melted a piston (looks like it had a vacuum leak at the bottom of the cylinder). I bought new pistons/cylinders - am working on replacing all of them - but what way do the arrow on the top of the piston go? In other words, what does it point towards?
Thanks for any info & thanks to the person who sent the link on how to remove my engine - had it out in 1/2 hour!
