Ok Storytime again. I upped my pilot and main jet. Here is where I am at.
140 main
125 pilot (all i had on hand)
2.3 N/S with 95g spring (im around 20-22 psi on popoff)
Check valves look to be good, replaced some loose fitting fuel lines and ran a line straight from tank to carb. Pickup is clean.
Got the ski dialed back in and now both the low and high speed adjuster screws are around 1 turn out. Much happier.
Still having the same issue.... I did some testing and this is what I found. When the ski is cold & not being ran hard, it will start back up right away. If im riding it hard and getting the motor hot, it wont want to start again unless I give it a shot of primer.
Is vapor lock a thing on jet skis? The only other thing I could think of is the reeds that I put back in were not the best but I have run far worse and haven't had an issue like this before. Maybe when the ski is getting hot the reeds are expanding & not sealing on start up?
Good news is I got it topped out at 34mph with a full tank and passenger. From what I found that is around what it should be.
