By the way, the serial number stamped on the block is 0877432 F255X.
From online documentation, the "X" in F255X indicates it is a 3100-3800 Thriftmaster 235 engine, leading me to beleive that the engine isn't a Blue Flame, and was just labeled as such a long time ago.
I'd still like to verify it though.
