My motor mechanic told me that I could greatly increase the life of my carbs and prevent some issues in there if I disconnect my fuel line from motor on the way to dock and allow the motor to run itself dry. Any thoughts on whether good or bad? I have a 9.9 tiller motor with a quick connect fitting to the motor, so easy enough to do. He says the benefit is that way there is not fuel sitting in there until next time I go out.
