I ended buying the motor. Had some trouble getting it shipped to me because he wanted payment by check. The engine spins up really nicely. The no run issue turned out to be some flakes of debris in the gas tank which were blocking the outlet. Pretty simple fix in light of what it could have been. He did a pretty cheesy job of plumbing the radiator. The outlets were JBwelded into the plastic side tanks! Needless to say, this will not last under my watch. Other than the radiator, his fabrication work looks good. I believe the "grease" was from leaking diesel. He washed the engine before shipping it, but the tank valve leaks so bad that diesel is already coating the engine.
