How to sell a used engine?

You said you ran it.
If it didn't make any odd noises, but just died at idle I'd be ok with it if the comp looked ok.


It's still connected to the transmission but it's sitting on the shop floor. I have no problem bolting the starter back up and hooking a start trigger to it to do a compression test, but it will only be a cranking test and not a running test. I know that makes a difference to some people.
