95 spi wont start+have spark+

[zero visual]

I have spark in both plugs, took off the airbox to see if the butterfly was sticking and it was clean as a whistle. fuel filter was dirty, i don't have a spare so i just dumped it out and placed it back in. It started last season. I poured a little 93 in the carb and it fire for a second but die then i dumped some more in which flooded it . pulled the sparks and cranked it a bunch and sure enough gas was tooting out of the hole. so now its sitting with the sparks out. I think its just bad gas so I am going to head to the store and buy a syphon.

try just spraying some gas in the carb and see if it will run that way

Youve only just begun... well go ahead and try to fire up with gas or starting fluid (but dry out your cylinders and spark plugs as good as you can first)... if it doesnt you need to start with the carb(s).. It it does fire up, you need to start going thru the fuel supply. Also you didnt say if you did a compression check. change gray stock fuel lines (a must for our year), clean out the rest of the fuel passages and inspect including filter, selector, etc and be sure no air is getting into any fuel lines and tank holds pressure. And then you will end up back at the carb(s). Cant leave carbs sitting for any period of time without possible issues. Put a see thru fuel filter inline before the carbs... seems like we all end up doing that to visually see we are getting gas to atleast that point. theres alot of locations that can prevent fuel flow to them, all the way back to inside the tank. good luck. im getting closer myself.

thanks for the replies!
alright so I ordered NGK spark plugs, I have read that the gray fuel lines do suck ass so I will be heading over to napa to pick up some of their injection hoses, now as for the starter fluid, does it matter what kind I use or no? Also I have noticed the previous owner disabled the fuel selector which kinda sucks but whatever no big deal. The carb on the other ski was completely rebuilt and this one was taken apart and cleaned etc.. I took this one apart and it does look very clean still soo.. it begins LMAO, I will be picking up a compression tester from Sears/Arrons, hopefully i get 150 in both BUT that most likely will not happen. if the rings are fried or anything, Im just going to get a 720cc and drop her in. O real quick, would a bad safety switch cause the ski to crank over and not start?

You can save yourself a bunch of money if you buy regular fuel line hose instead of injection hose, works just as well.

I dont know where you live but i got fuel line (25ft) for less than a dollar a foot (Orchard Supply Hardware). and got a compression tester at Harbor Freight Tools for cheap. You have any of those stores around you??

Man, I wish I could just go pick up and drop in a replacement 720 motor and new carbs and be done with mine!!

 

[TFWildman112]

don't use starter fluid gas is all you need. starter fluid and oil don't mix and will burn up your cylinders it's "starter fluid" not running fluid. lol

thanks everyone! I will be getting everything tomorrow. Hope it starts

alright, i pulled the gas tank and got all the nasty gas out of it, reinstalled and then dumped some 93 in it and it fired right up! ran for about 15 seconds then died out, fired it back up did the same thing. My guess is the old fuel and everything is starting to run through. I went to start it today, but was a no go. battery is dead going to get a trickler right now as we speak. Also I have new NGK's on the way, these had autolite in them.

Was just thinking about this and my girlfriend mentioned to me about priming the fuel filter etc.. When I reconnected everything I never primed the system. So I will be giving that a go tomorrow. Also what size fuel lines do i need? 1/4"? 5/16"? both?

 

[LouDoo]

You shouldn't need to "prime" the fuel system, just use the choke. All of your fuel hose is 1/4", 20' should be enough. I use 1/4" quality cable ties instead of clamps, I think they grip better, are easier to install, and remove easier. The last cable ties I bought I got Panduit brand at Graybar Electric. Get the black ones, they're UV resistant. Also you only need to replace the hoses in the fuel delivery system and the pulse hose, you can leave the vent lines alone.

Most autoparts stores, Advance, Autozone, Pep Boys, carry the NGK spark plugs in stock.

ok, alright heres what i did. I ended up hitting the fuel filter with some carb cleaner and it cleaned up nicely. But again no starting. I have ZERO fuel running through my lines yes they are still the grey ones. I will be grabbing some hose tomorrow. But again i pour some fuel in the carb and sure enough it fired right up. Also, is there a diagram that tells me what connects to what in the baffle? I do have the seadoo manual so thats not a problem. Also if its not the fuel lines then what? I should pull the carb and see if its gummed up?

 

[TFWildman112]

make sure you checkout the fuel selector too. idk know if this will help: http://tinypic.com/view.php?pic=16kccw9&s=7
Use a clean rag to wipe any fuel residue from the lines. On the fuel baffle right below each line is marked to where the line goes i.e. ven = vent, res = reserve, ret = return, and on well it's on. These 2 things together should straighten ya out!

 

[LouDoo]

Check out this thread, it tells all you need to know, maybe more, about fuel delivery problems.

BTW, check your main filter, I speak from experience, carb. cleaner melts the plastic mesh., I ruined mine.

Alrighty! The new fuel lines are in, I let the fuel selector sit in some PB blaster and is back to working order! W00T! Cleaned the baffle screen also fixed the magnet in the baffle and set it with some JB weld. Primed the line by doing the old school syphon with the mouth LOL and I got a mouth full of gas. After making sure everything was connected properly and snug, still no fuel being sucked, SO now on to the Carb. I will be pulling it tomorrow morning and hopefully when I crack it open, its still in working order and all that needs done is to clean those filters. Anyone have any thoughts on this?

 

[TFWildman112]

isn't the carb also a fuel pump? you may just want to get a rebuild kit and tear it all apart while your there and replace all your gaskets and seals and clean the crap out of it. make sure you take your pilot jet and main jet out and clean all the lil hole with a piece of wire top and sides.

yeah the carb sucks the fuel in. I about to go out and pull it so HOPEFULLY everything is still in working order and I won't have to rebuild it. Hopefully I just need to clean those 2 little filters.

Well, everything was looking awesome inside the carb until I came down to the filter. Thing was nasty gunked up! Cleaned it, slapped it back on and then nothing... go mad and decided to dump some gas into the carb and boom. runs perfect now! fires up beautifully. Thanks for your help everyone. Now On to the seats. Where should I buy the seat covers?

 

[zero visual]

throttle was sticking on the other ski, so pulled it smoothed it out with a stainless steel pad and works like a charm. Also ordered my seat covers. Should be here soon.
