1986 Johnson 140 v4

[Glas23]

Hey, I’m hoping to see if anyone has any pointers for me on my Johnson outboard. When the boat is first fired up on the lake the motor runs perfectly at idle and full throttle. If I turn the motor off for some time to swim as soon as the motor is turned back on it is completely bogged down sometimes it will come back to life after some time. Any info would be appreciated!

Take some tools with you and check spark when it acts up
