Ok, I have been on vacation this week and mostly trying to enjoy the Seadoo. I've been successful and the weather has been perfect here. I took the ski out of the water one morning just to check some thing's for a couple issues I am having. One is difficulty keeping it running on warm restarts after sitting for at least 15-20 minutes. I leak checked the carbs and they are not leaking. I have some more things to check on for that latter. The other issue - and they could be related -is a bog/hesitation from idle. So while I had it out, I checked the a-pump nozzles to make sure they are giving good squirts. I checked this extensively and the nozzles appear to be clear and open. The only thing is the a-pump seems to be iffy on whether it has a prime or not. It seems to come and go. I have checked the inline check valve after the pump for proper functioning and it is. Is there another check valve anywhere else? Can anyone list issues that may cause the a-pump to occasionally not pump? I know several of the most obvious things but most of these have already been checked. I am interested in other things in the carbs themselves that could be starving the a-pump from fuel.
Would a small pin hole in the a-pump diaphragm cause this symptom?
