  • 03 50hp 2stroke prime start enrichment

    Have been trying to solve problem with no luck. Choke on key switch does not seem to work. Emerg kill switch wires hangs loose when got boat. Cranks and starts for few seconds but dies sometimes squeaks back thur intake as dies. Can flip prime start enrichment to open emerg start and will take off ok as speed gets up flip back to normal position and will run perfect only at 3000 rpms. Stop boat to idle, and won't go under load to take off again without jogging accellerator real fast back in forth or flip back to emerg position on switch. Bulb on prime flattened out once its a cheap walmart one looks like junk. Soon as flatten out it popped back out. I blew thur hose to inboard tank it was open. Iv ripped down all three carbs down blew out and all are super clean. Could be air leak in intake somehow. I'm stumped

    Is there as reason you are trying to hit the choke and your motor does not have one if it is a prime start motor?

    Your pilot/idle passages/jets are plugged , disassemble completely and soak in carb cleaner and blow out with compressed air. Make sure you do the link and sync just like the manual says after reinstalling the carbs
