First off, let me just say one word...UGHALKFLALKDHA
That's better.
Long story short - 90' JS550 with a milled head. Great compression (~150 in both). The ski has been sitting for 2 years in a garage since the last start up.
I replaced all hoses and lines, new battery and drained all the old fuel. Then I started on my journey.
I have been able to get the ski to run but it will not idle even with carb adjustment. As long as I keep giving it gas it revs out just fine. It's also really picky about when it wants to start. I'm getting plenty of fuel. My spark seems to be a good blueish color. Here's the tricky part...
I fired the jet ski up and had a friend throttle it. I removed the rear plug wire and the ski seemed to run exactly the same - same sound and didn't even seem to be missing. I put the rear plug wire back on and removed the front - it started missing.
It seems like the ski has been running on one cylinder the entire time since there was not a noticeable change after removing the rear plug wire. I'm thinking that's where my problem is. Any ideas on what to test? I know the CDI could be bad but wouldn't that affect both cylinders?
