Here is a shot of the engine all apart. I found a cracked piston and the cylinder was a little scratched up. I'll have to replace the piston of coarse, but the cylinder can be honed out. I also found a few wore out shift dawgs in the transmission. The gears and sliders are rather expensive to replace, but I can salvage those out of the other wrecked engine. The oil drain plug threads were also stripped out. I will have to tap them out to a bigger size.
