I bought one similar to this (Complete) for $250. Seller said it was .010 over ran good when pulled ect...I opened it up it was .080 over with very bad cylinder walls...unless you run it or open it it's like a Cracker Jack prize (Unknown). Luckily the carburetor, started & generator were good. Also the Intake/exhaust. The head was "848" and not cracked. Those were worth the $ but I was out a block.
