150 4 stroke primer bulb question. Serial #2B467082 Do I need to remove the primer bulb? I have read the installation manual and I cannot find any mention of primer bulb except "run out of fuel condition" Priming the FSM it says "if a primer bulb is installed it can be used during the priming event to shorten the amount of time required to start the engine" If I need to take it off I certainly will. Do I replace it with a piece of tubing?
