alright well if this is the rotary valve then it fell of...lol woops. So once i got the cover off i turned the motor over and either water or gas just poured out of these two holes. I would guess about a quart of water/gas atleast. and the gear that sticks out does spin when i turn the motor over. Looks like i need a degree wheel to get this rotary valve back on correctly, any tips on that?

Ya that's the rotary valve. Now you will need to re-time the valve. Service manual will show you how.

When you run it on the hose did you start the motor then turn on the water? If not that would be why there's water in the crankcase.

never ran it on a hose. hasn't ran for more then a few seconds since i've been trying to fix it.

Remove the two 5mm allen plugs on each side of the lower oil hose , that will drain all the crap out of the engine, most engines don't run well when flooded or full of water. If you look closely there should be a line scribed into tghe rotary valve face on the engine, you put the front cylinder at TOP DEAD CENTER and put the valve back on with the cutout facing toward the front of the ski and the upper edge of the rotary valve cutout lining up with the mark, if there is no mark its degree wheel and mirror time. This is why I said don't let the rotary valve come off when you remove the cover.

alright ill do that. thanks alot for your help, hopefully water in the case was was my problem the whole time???

 

[chips]

you wont ever believe it, but it STARTED!!! then i started putting everything back together and the battery died so i couldnt start it again. im assuming ill have to start then pull the plugs a few differant times to get all the water out of it, but hopefully this fixed my problem. any other tips on clearing all the water out of this thing? also when it fired and ran a puddle of oil was on the ground about the size of a basketball. i'm assuming this is just oil from it being flooded out so bad?

 

[WFO Speedracer]

More than likely the inner crank seals are bad letting oil seep into the bottom end , after all they are 1994 model oil seals.

finally rode this thing around the lake this morning. ran good. only problem now is i have to go wide open throttle for it to start. im thinking its too rich on the bottom end. It didn't have any punch on the bottom end while ridding it either.

 

[WFO Speedracer]

Either you have the low speed screws way too far out or the needle and seats are leaking, at least its running now lol

 

[chips]

Was running. Wtf. Bring it back and now it won't start again. Pull the plugs and they are wet every time. But getting spark. What now..

took these carbs back apart because i think i have a problem with them. Because when i pulled the pulse line off the fitting the ski started up? dual 38's and did the little test where you blow in and suck out to make sure its doing what its supposed to and on the carb with the pulse line all is well but on the carb without the pulse line the fuel out line no air goes through it either way? normal or something wrong? ive blown air through it and cant get anything. all the diagrams ive found just show testing the carb with the pulse line but i cant imagine this is right

 

[WFO Speedracer]

Sounds like the return line is stopped up, the return has a small passage drilled into the body to restrict the fuel returning to the tank, it would be quite easy to stop up and would also cause the rich condition you described of having to hold the throttle open to get it to start, when you removed the pulse line and started it you created a giant air leak which leaned it out enough to start normally.

 

[chips]

how would i go about unplugging it? i tried everything, Carb cleaner, compressed air. any other ideas?? this is starting to kind of make since.

 

[WFO Speedracer]

A small piece of wire or a jet drill

Sounds like you need to have a 5 gallon can of gas and matches party....

i agree!!

Alright i got the return line unplugged and it is still doing the same exact thing...... I can get it to start and run for a few seconds then it will want to bog out unless i give it gas. will not idle. pull plugs and they are normally both wet with oil/gas. if i pull to pulse line from the carb and turn it over gas/oil spits out of it. Im out of ideas again. if i clean plugs, blow out cylinders it will normally fire right up without gas but will then die if i dont give it more throttle. i thought forsure the plugged return line was my problem, or maybe it is but there is alot of residual oil/gas in the case??? HELP!!!

Have you checked the popoff on these carbs?

 

[chips]

i dont have a pop off gauge. but everything is new

 

[WFO Speedracer]

Without a popoff gauge you are shooting in the dark, double check the levers that open the fuel needles, if they are out too far the button on the diaphragm could be holding the needle and seat open slightly, I usually check the popoff, install the covers and check it again, also on Seadoos excessive rotary valve clearance will also create a rich running condition that no amount of rejetting will fix
