Posting for a friend: New coils, new spark plugs both sparking. Bypass kill switch no change. Cleaned carb, .005 valve clearance. 190 compression and passed leak down. Rods are straight. Any ideas? |

Check the diodes that connect to the coils. Sent from my SAMSUNG-SM-G935A using Tapatalk |

If it's cylinder #1 I've seen the the vacuum fuel pumps leak fuel into the pump signal line flooding the num1 cylinder |

He says his engine doesn't have diodes connected to the coils on his engine and if you're standing behind the boat it's the right side not working |

That would be cylinder number 2. That eliminates the possibility of the fuel pump. Next I would remove cowling and inspect the intake gasket going to the head. Gasket may be popped. |

Turned out to be a bad oil sensor |

Problem was just in the carb setup. It's alive and running good now |

Found that I am having the same problem. Right side standing behind the motor doesnt appear to be firing. What did you find in the carb setup that created the problem? I found mine not firing when trying to adjust the idle. I cannot get the motor to idle properly at all. |

When it came in I noticed a idle fuel screw broken off in carb. Set valves, it passed a leakdown . I got the broken screw out and freshened up carb. Ran good after that |
