I got this motor from Craigslist. The guy who sold it to me started the motor and it started on first pull. However the test was done without water. Only ran for a minute. I purchased a new fuel tank, fuel line etc and got some water in a trash can and tried to start. Although it started eventually, it took several pulls. After turning it off, it would take several pulls to start again. There is a red light below the starter cable that is lighting up when I pull. What should I be looking into? What are the possible causes? Thanks for the help.
