96 xp not getting fuel after fuel line swap

[clemchilds]

Need help please, I just finished cleaning the carbs and replacing the fuel lines on both of my 96 XP's. After compleation one of the skis is not getting fuel to the carbs. I sprayed starter fluid into the intake and got it to fire up but it would still not pump any fuel into the carbs, Could I have messed up anything in the carbs to cause them to not pump any fuel? This ski was running but not very well before I started this project.

Thanks for any help!!!

No starter fluid

Do not use stater fluid in the engine, these are two strokes and it needs a gas oil mix!!! You can do damage to the motor if there is no oil.. What I do is put a small cap full of gas in the carb, I use the yellow cover that comes on the gas can.. You need to get the motor running for a minute to get the pump working in the carb.. The pulse line uses vaccum pressure from the crank case to run the pump.. It takes a minute or two to get the fuel moving in the system.. Use a 40:1 mix...

Thanks for the info, I will be sure not to use starting fluid again. I have been trying to get this running more tonight and I have been able to get it fired up and it will run for a few seconds then it acts like it runs out of fuel again.

I hate to state the obvious, but you are talking about replacing 25+ feet of fuel line. Are you 100% sure you routed them all correctly and that they are all connected firmly?

Sorry to sound belittling, but often it is the simple solutions that befuddle us (sorry to use the word "befuddle" but it fit just perfectly in this sense...:ack.

Also, there is 25+ feet of fuel line that will need to be primed before the engine fires and stays running, so priming those carbs may get the system primed and pressurized and running. So use that 40:1 mix to prime the carbs 3 or 4 times and see if the system doesn't pressurize and run.

(between you and me, I used starter fluid...:reddevil: the brand I use has an "upper cylinder lube" added. Still not as good as 40:1, but on this old 96 XP, I could care less if it seizes any time soon...) I would recommend the 40:1 in a spray bottle or squirt bottle.

Thanks for the info SCOOPER77515, I am sure that I have all of the lines ran correctly, however I am not so sure about having them all as tight as they should be. I will check this first thing tomorrow and try with the 40:1 mix.

Thanks again.

Did you hook up the pulse line?

i had the same problem...another member told me to disconnect the hose that connects to the carb and blow INTO it and listen for bubbles or somethign in the gas tank...then siphon from that same hose...you should hear and see it starting to fill up the filter cap and then after awhile it will flow all the way. I hooked up my siphon hose to the fuel line to help

I know my rookie status is showing, but where do I find the pulse line and where does it connect?

Thanks again.

It's the small hose that goes from the fuel pump on the front carb to the crankcase. It operates the fuel pump.

Check the filter

One other thing check the filter under the hood and be sure the gasket is good and seated.. If it is not you can suck air from there and it will never start.. You can replace it with an inline fuel filter.. You can get them anywhere, autoparts store, Walmart etc..

Good point, and I did just this. My filter was actually "stripped" and just about the time you would get it screwed on tight enough to seal, it would jump the threads and be loose again. I just got a cheap plastic inline filter from O'Reilly auto parts, and used wire ties to keep it up and not bouncing around in the hull.
