Hi everybody I am kinda stumped with this ski. I recently picked up a 1997 seadoo spx that had VTS problems which I fixed.I changed all fuel lines, rebuilt carbs, flushed all fluids and changed spark plugs. I never got the 2 beeps but I assumed the buzzer was bad because the ski has always ran great. Long story short I took the ski out this past weekend and it started up normally and ran long enough to get out on the lake and than ran like it had dirty carbs again and then just died. If I let it sit it starts for a second than dies. I checked the carbs and filters again and they are still clean. I checked the plugs and they are wet so I know its getting gas. I don't know maybe week spark or mpem problems?? Any help would be greatly appreciated.
Thanks: confused:
