1996 XP Stops Running After 1/2 Tank

[ghebert1111]

I've got 2 1996 XPs and I'm trying to get at least one of them running right before the end of the season. So I fill up my one ski with gas and it starts and runs fine and then dies when I've burned about half a tank of gas. I've tried it several times, starting with it full and it will die after running it down to about half full. I fill it up again and it runs just fine. I'm assuming it's something to do with the baffle but don't know what the issue?

Thanks in Advance.
2nd ski issues coming in another post.

Maybe the baffle is broke or cracked somewhere at the mid point? Would cause it to suck air and it quits. First I've heard of this half tank issue, I'd pull the baffle and have a look.

I'll have to report back this weekend, the ski is at the lake.

When it stops at half tank open gas cap and listen for a loud hiss. If it does and it cranks and runs, then your fuel vent is clogged and/or not working. If it is stopping at exactly the same level, then like was said, I would suspect an issue with the baffle.

I was able to pull the baffle. I dont see any cracks. Small holes at the top and bottom that seem normal.

That baffle has definitely done its share of sitting in old gas. Take the screen off of the bottom and inspect the internal tubes that run to the on and reserve nipples

Looks fine inside. I tried filling up the the internal tubes and they seem fine however I think I'm gonna get a rebuilt one. On the plus side I now know how the reserve tank works.

Is the fuel filter full? Try bypassing the petcock. You could also try rigging an external fuel tank, and run it straight to the carb.

I'll post back on results of the new one.

I will try this this weekend. You're talking about the water separator,correct?

He is talking about the ON/OFF valve or "fuel selector".

Thanks miki, us older folks with our older terms

Ahh, well I'll be bypassing both on Saturday.

Well, bigger things to worry about; the Mag-side compression dropped to 60. At least it's the end of summer. I'll have to deal with that and then worry about the baffle. Thanks for everyone's input.
