Had a miss develop. Cdi, stator, rectifier and trigger replaced with NOS components. All wire colors went to where they were.

Runs good now without misfiring.

A bit confused when I went to check the timing and the timing light shows the marks on the flywheel are on the back side of the engine.

The flywheel only goes on one way with the Wilson Key on the crankshaft.

Not really sure what may be amiss. Maybe the replacement stator, cdi, or the trigger had opposite side wires wrong.

Any thoughts or ideas? Thinking i could try to swap stator leads, trigger leads or ignition leads with plug wire swap.

With timing out by 180 degrees the motor would not run.
That's what I would think as well. Been on the lake twice with it, since the change. Will pull the flywheel when I have time and check the key on the crank to make sure it's not sheered off.

Would a flipped stator caused this? If it's anything like my '85 85HP, it would be virtually impossible to bolt it up 180* out due to wire lengths, but I don't know if the 50hps are any different.

Had to replace the stator on mine this weekend, and had a pause moment when I realized the symmetric bolt pattern could make it very easy to bolt that thing up 90* out of position, more so if the stator was new and the wires hadn't taken a set yet and the only clue I had for up/down was witness marks under the screw heads on the used parts
