NBR:

This is exactly what the mechanic said. When the motor heats up and then cools down condensation accumulates inside. I'm not sure why Fuel Injection is not prone to this problem, but according to this knowledgeable guy it is. He told me that the way I should handle the carb motor is to take any gas left in the plastic tank at the end of the weekend and pour it into my car gas tank. Then I should run out the motor until it stalls. Does anyone out there use a 4-stroke 25 horse Mercury with a carb? I'd be curious to hear about your experience.
