Fuel in the oil? What carb setup? Fuel pump? Pressure?
Sounds like could have washed the rings out with fuel or thinned the oil out so much there was no lubricity left and took out the bearings. Either way, not good. First thing I would have recommended was the compression test and you did that already. What kind of rings are you running? Maybe do a leakdown test also.
I'm afraid you already knew this and sounds like your gonna have to pull her. Hopefully it's just a matter of changing rings/bearings.
Any metal in the oil when you changed it? What oil are you running? Only 100 miles did it have break in oil in it with a zinc additive?
