What should I look for as far as checking it out before I buy. I'm going to purchase a compression guage to check that (please post instructions how to do so.) How much should I look to spend (right now the guy is several hundred over NADA.) I know the electronic choke is non functional. I have seen the engine run. The guy says the compression is 150 +/- 8% all around.<br /><br />Thanks in advance for your advice,<br />John - Temporarily dry docked in FL
