I may be buying this motor and I need assistance in evaluating it. I am non-mechanical guy with basic knowledge but wanting to learn. The motor apparently has been in storage for 2 years. The controls come with it, but no prop. I do not have a compression tester. It appears to have the usual scratches and wear of an older engine. What tests would you reccomend I do to test this enigne. It is not likely that I will be able to stick it in a barrel of water to test. Thanks for any help you can provide.
