Polaris xlt

[Tanner]

I know this is automotive but I wasn’t sure where to post this

I have a 1994 xlt snomobile 2 stroke 3 cylinder

I ran seafoam through it and it made it run great ( it was bogging down on the bottom end) after running for a while I trusted it it was running actually quite nice so I thought I’ll let it run and ill go up the road to feed the horse maybe 100 yards up the road I came back and it had died and would start and run on what sounded like one cylinder for a short time. I pulled the plugs and looked at it and found a milky white substance in the cylinder and plugs head gasket maybe? I don’t know what else it would be?

O also before I put the sea foam in it the RPMs liked to climb by themselves and if I turned the choke on it brought them back down

[Jared Thomson]

Air or water cooled?

[Jared Thomson]

I did some research and it sounds like that milky build up is normal for seafoam in 2 strokes. Try changing your plugs and switching back to regular fuel/oil mix.

[Tanner]

What about the oil injection? And it is water cooled

[Jared Thomson]

Well, if its oil injected you dont have to mix. Just put fresh fuel in, or you could try to keep burning the seafoam. maybe clean off the plugs with some gas?

[Tanner]

I cleaned up the plugs and put some gas in but it’s like 85 octane I wonder if a higher octane would help it

[Jared Thomson]

Probably not, unless the motor calls for it. Higher octane fuels are for high compression motors.

[Tanner]

Well I’ll see what I can do with it

[Jared Thomson]

Let me know how you make out.

[Tanner]

This is what I found if I clean the plugs and put fuel in the cylinders it will start right up and die after a sec so I kept doing this and most of the white gunk seems to be clearing up even gone sometimes but it still won’t start and run on its own. So I took the fuel line off and it smells/looks like gas but not much was coming out of the line. So I looked closer and just behind the gas shutoff valve there is a white thing a couple inches long I’m thinking its a fuel filter maybe its plugged up any ideas?

[Jared Thomson]

Can you send pictures? I would say you have a carburetor issue, take the carbs off, clean them out, check all the lines/replace filters, and adjust the carbs.

[Tanner]

What’s the best way to adjust them on a triple? I know on a dirt bike you adjust the idle screw but how do I adjust three of them

[Jared Thomson]

Its a really complicated process, so I would start with cleaning everything, and adjust down the road if you need to.

[Tanner]

Ok I have never tore into a carb but ill look at some diagrams and stuff and maybe check it out

[Jared Thomson]

Yea, carbs aren’t too bad, just from what I understand, if you don’t get the carbs synced right, the motor will tear itself apart.
