We went over the weekend to pick up the parts haul from the same guy I bought my 317 from.
100$ for a mint 140 seat, really nice 212 hood with 3 intact mounts and one that's pulled the bolts out but is still in one piece, one single awful side panel from my 317, a motor, what's left of my brother's 300 minus the engine, a steering wheel for his patio 140, a transmission speed control handle, and a headlight lens.
My brother's 300 is for parts, so I stole the steering wheel, rear plate, the intact brake pads and drum, and the choke cable, and my brother took the front lines, front plate, H2 valve and handles, and the front tires.
We will be selling what's left, which isn't much, just the bad transmission and the steering components.
So about the motor: it's a K321 from a 214. It's...seen better days. It has had a fuel pump replacement, which went on with no gasket, and of course leaks like a sieve. It must've ran without oil, the original owner decided to run it till it blew up, then rebuilt it, even worse than original. They added an insert to fix the excessive tolerance on the crank, replaced the whole piston, and honed it.
EVERYTHING THEY DID IS WRONG.
The insert was added onto the heavily scored crank, which of course was grabbed by the ridges and it began spinning the insert.
They honed it incorrectly by shoving the hone in and not moving it at all while holding the button on the drill, so the crosshatching is horizontal.
The motor, to no one's surprise, threw another rod after just about 4 or 5 hours of running.
Luckily for me, it threw both rods into the oil pan, which ruined the pan and required RTV, Silicone, and a pan gasket to seal after the first thrown rod.
Good thing we have a 140 crank and piston I can use to replace the damaged ones, so I guess I'll rehone the cylinder and reuse the new piston head from the 214 motor and the rod and crank from the 140 motor.
