johnson 150 wont stay primed

[bassone75]

2001 johnson 150 carb motor. Wont stay primed after I shut it down for a bit. Also when I prime it back up sometimes it floods it. Any help on this would be great. Thanks

depends how long its shut down for as to whether thats normal.
flooding sounds like a weak float/ sticky bad carb valve, keep priming with engine tilted forward a bit and see which carbs involved

Have you checked around the carbs for any leaks as that motor should have the plastic carbs.

About thirty minutes after i run it. Carbs were rebuilt this year but not saying that something still couldn't be wrong with one. I will do as both of you mentioned and post back what I find. Thanks to the both of you

You'd think there would be enough fuel left in the float bowls to start it.

For me, it depends how long it takes to start:drum: and whether youve tilted the motor up while youve stopped
