Ran car home VERY RICH 10-1 on E85. Did I do any damage?
See sig below. I'm running a Garrett GT series turbo combo. I was out last Friday doing test pulls. I had my AFR right at 11.0-1 (E85) which was my target WOT AFR. It all of a sudden got pig rich. (Junk in the needle and seats). I drove it home which was about 5 miles and it was dumping fuel. I took the carb off, cleaned it up and put it back on. The starter couldn't turn the motor over. I only tried this once. Next time I get to the car I will pull plugs and turn the motor over by hand to get all the fuel out of the cylinders. My question is, did I hurt anything by doing this??? I'm really worried about bending a rod with the starter or something like that. (This didn't happen while it was running. I did get it home back in my driveway.)
Any help guys?!?!

Excess fuel will wash the cylinders of oil. Especially since it sounds like it hydro-locked the engine. It's unknown how much or if any wear occurred.
Excess fuel will also kill a catalytic converter (if you're still running one) real quick.

You could have bent a connecting rod, cracked a piston or head.
If you pump liquid out of the cylinders, at the very least you contaminated the oil.
