98 115 wont start?????

[jeremy5780]

1998 115 v4 crossflow rebuilt approx 1 yr ago 112 psi all 4 cylinders. Just rebuilt carbs I know its getting fuel, when i take the plugs out there wet with gas. It is getting spark when i take plugs out and lay against block there is good spark. replaced the stator still nothing. I did get it to start the other day but i had to keep cranking it for approx 20 to 30 secs then it ran for a minute but it sounded like it was missing and would not rev up with out wanting to stall. I took it out about a week prioir to this and it ran great until i almost ran it out of gas and i think it had water in it. as I was headed inthe motor was wanting to die unless running wide open. then when it would die it took me a long time to get it running again then as soon as i gave it gas it died. but back to the non starting issue. i dont have a multi meter so i have not done any tests in the book yet. Could it be the timer base under the fly wheel? Thats about the only thing left, stator is fine power pack is fine. ANY THOUGHTS???????

have you done a link n sinc, since you have done all this work? are you sure the plug wire are in the correct positions. motor has to turn +- 300 rpms to start.

What makes you think there was water in the gas? If there were that would have been a problem way before running out of gas.

Have you drained or replaced your fuel/water separator?

You say it's getting gas, maybe it's getting too much gas. When you pump the primer bulb, does it get hard?

Pull the cover off the carbs and see if you see any fuel flooding out when you are trying to start it.

Also, make sure your primer is in the Run position, and see if you can hear it click on and off when you push the key in and out. I guess it could be possible that the solenoid could get stuck and be continuing to prime it, hence flooding it, but it would probably at least start cold then.

There is an excellent thread in the FAQ's by JB entitled Outboard Wont Start, follow it step by step, and let us know what you find. Not really enough information yet to properly diagnose your problem.

Re: 98 115 wont start?????

as far as the outboard wont start forum cant find it. I went out and messed around a bit as this is pissing me off. Tried to start it a few times with no luck. I have it hooked up to a portable tank, i checked the primer ball it is getting hard. I looked and listned as i pumped it and there is no gas or air coming from around the carbs. But after i try to start it I can smell gas and it seems to be flooding itself. So i took all the plugs out and cranked it for a second great spark on all the plugs. Put them back in and it fired right up but it was reving up and down so i gave it some gas and it reved right up. Shut it off and tried to fire it right back up and nothing!!! So i think when i took the plugs out and cranked it all the flooded gas from the cylinders escaped and when i put them back in it fired up. But why didnt it start after running for a minute? could it be my fuel pump? it is really the only thing i have not touched since i have had the motor. As far as the linc and sinc i did it the butterflys are both closed the carbs are rebuilt and i know the needle is seating beacues i tried to blow and suck on them with it turned them upside down

When you rebuilt the carbs did you check the float position? If the float is set too high it won't shut off the gas causing flooding condition. Your blowing and sucking just proved that the valve closed, not neccessarily where it's supposed to.

Re: 98 115 wont start?????

well went out this morning after letting it sit all night. I did not pump the primer ball and it fired up it did however rev up the diedown it did this a few times then wanted to die so i let it. I belive this is a fuel problem. I guess i will take the carbs out and check the floats. even though they have not been messed with for a while and it was running great. do they go out of wack after a while??? I read two diffrent threads about float level one says the float should be exactly alligned with the bowl. Which is how it is now. the other says it should be ever so slightly lower in the front, oppiste the needle and seat. would this really make all that big a diffrence? any input would be great. thanks

Re: 98 115 wont start?????

Just a few thoughts, but maybe something from your almost empty gas tank somehow found it's way into a carb and lodged itself where the float or something is allowing too much fuel to enter, and flooding itself out.
You didn't say if you checked the primer yet, something could be wrong with it and maybe it's continually priming the system, causing a flooding condition.

Re: 98 115 wont start?????

I dont know abouth sucking somthing up i cleaned the carbs pretty through I also the 3 filters it would have to pass through. I dont belive there is anything wrong with the primer when i push the key in i can see the gas flow through the tube and when i stop the gas stops. i guess i will check the float level although i dont think it if off and if it is i dont belive it is enough to cause this eratic behavior

When you say you're getting "good" spark, what does "good" mean. It needs to jump a 7/16" gap, either with a home made tester or one you pick up in the auto parts store. It could look good, but unless it is strong enough to clear the 7/16" gap, it may not be doing the job.

Although the eratic idle, doesn't sound like a spark issue to me.
