Weird thought here.... Those problems don't sound like Dead cylinder problem. Hard start but runs fine and reaches top speed does not sound like Dead cylinder.

I have a humble cheap suggestion. Get a spray with fuel oil mixture and spray it on the carbs on next hard start. If it starts right away it's a fuel issue.

Carb rebuilds were notoriously difficult for me to get perfect after much tinkering. My seadoo had 1 carb per engine, so i bought them from mikuni new for $200. But i only had 2 carbs.

I bet the issue you describe is fuel related.

But the test compression was reading 0 and 120 on the pther 2

Any chance that zero was a misread? I would think engine would be weaker with a dead cylinder.

It wasnt a miss read i did it twice on all 3 and same 120 .0 120

Wow. Very surprised you have such great performance with a dead cylinder. Might still be worth a try if you want to go out before you rebuild it.
