Seadoo Challenger 787 Put Putt Putting? Watch the video

[JohnMetta]

Good Afternoon,
Started up one of my engines and it's sputtering. Not sure how to explain but watch the video. Just doesn't sound right. The other engine idles smooth. What could it be?
Thanks,
John

I can't help you on this one.
But I see a white sparking light flashes in front of the mag plug where the right side hose attaches to the motor.
Is it a reflection or what???

Looks like something swinging and making a reflection. This iPad is so hit and miss on the Internet. I am getting no sound from the video.

I'm not actually sure. I think it may be a plastic piece to hold a temp sensor wire. I took the video earlier and unfortunately I'm not near the boat for the rest of the day.

Sounds like a 2-stroke from where I'm sitting.

You can't tell anything out of the water.

I wish i videotaped a little bit longer. I don't know if you can hear it in the video but it keeps sputtering. After a little while, the RPM's would drop and pick back up. Cleaned the Carbs already. Plugs are one season old. I'll replace them. I'm not sure what a misfire or a backfire sounds like on these engines.

Great, now our work computers block anything Youtube... I charged my laptop last night so I will be able to see and hear them tonight...

Oh yeah Doc, congrats on the 10,000 posts. I figured you hit it last night when I saw 9995 early in the evening.

Replaced spark plugs and runs fine. Noticed the gapping in one wasnt right.
