Hi my name isXXXXX will assist you.
The first thing to consider is the age 34 years old . Then you never want to buy a non running engine that you cannot water test. I would look for something allot newer that is in running condition. You can't always believe what a person is telling you the engine may have a more serious problem. Customers are not always mechanics and have no clue most of the time what is wrong with there engines.
