I initially made this video to diagnose a no spark issue with my Seadoo. I was confident that was the problem because I had the Seadoo running out of the water before I took it to the lake, but once I got to the lake, it wouldn’t start in or out of the water. I tried putting starter fluid directly into the carbs, and didn’t get them to fire up. I thought I was getting fuel to the engine, but it wouldn’t start, so my next thought was spark.
Before I took it to the lake, we got it running in my driveway. My brother had rebuilt the carbs for me, but he hadn’t done anything like that before, and I’m starting to think that he may not have cleaned them out properly, and the carbs are still the problem.
One weird thing is that the seadoo won’t fire even when I put gas and starter fluid directly into the cylinders. I assumed I would at least get a few rotations out of the engine with fuel directly in the cylinders, but it wouldn’t fire at all.
In the video, you can tell it takes some time for the seadoo to fire up. It finally does, and I let it warm up for a few minutes at idle. Then I give it some gas and it doesn’t seem to hit the RPMs it should be. (I’m assuming this based upon the sound I heard).
I worked on it last night, and got it running in the video. When I went out this morning, it fired right up. I think this was a carburetor issue, but want to know for sure.
Do any of you have thoughts?
I’m going to run the machine out of the water for an hour or so and make sure I’m getting good gas flow through the carbs.
If the machine doesn’t run right, I’m going to rebuild the carburetors.
