Need a sled expert -- I have problems

13 posts in this topic

Ok I will try to make a long story short.

I have an 03 700 polaris --

Last year a buddy of mine helped me "winterize my sled" He goes a little more crazy than I do to winterize. Anyway he it Goes.

Last year we shut off the gas and ran it till it was out and died. Then we put oil in the spark plug holes.

This season I tried tostart it off of the bat and I did not go -- I forgot to turn the gas back on. Got it on and got it running.

The last two times I have had a tough time starting it.. It barely turns over like the battery is dead -- new battery this year.

This time I opened the hood and as I started it gas was coming out of the spark plug holes (cylinders)?

My buddy told me to take out the plugs and try and turn it over. It will clear the gas. Then put them in and start it. Let in run for a really long time and ride it -- that will take care of it?

What is going on?

What kind of problem is that?

Please help. I will post this in the snowmobile area as well, but I thought this area will hit a better cross-section of people.

thanks.

sounds like when you winterized it you forgot to tighten up the plugs.

Did you use motor oil or fogging oil in the cylinders? If you used motor oil it can get very thick in cooler weather and slow down the cynlinders, and you most likely fouled a spark plug. Is this an Direct injected motor? Change out the plugs and top off the tank with premium non-oxy gas (this is the only fuel you should be running in a sled anyway). If you have a carbed model, any fuel residue may have varnished and caused your carburators to stick and they might need to be cleaned up.

Good thoughts but not plug related and not Fuel Injected.

check at the bottom of the crankcase for a drain plug,there should be one for each cylinder.I ussually have to pull these plugs on mine when i take out of storage.There is ussaly quite a bit of oil in the bottom of the case and will take abit to purge out before it is dry enough to keep the plug from flooding out.Good luck,Burl.

When you say not plug related are you sure, did you put new plugs in? A plug that has lots of spark when you are cranking it over looking at it may not have enough when it is back in the engine under compression.

Leaky needles and seats on the carbs? Did you ever trailer it with the fuel valve in the 'on' position?

I think you have a carb that letting gas by. Thats from a improper float level, warn inlet needle & seat, or a piece of crud in the way.

This was my response to your same question in the snowmobile forum:

Quote:

If you let it sit and you have gas in the cylinders like that, its almost got to be stuck needle/seat. Probably dried out from when you ran it dry on gas (I'd never do that) rather than fogging the carbs.


I agree with 'lawdog' and would start my search here.

If the fuel inlet valve (needle/seat) is stuck down, it will continue to pump gas into your motor and you'll flood out. A flooded motor is obviously hard to start and you will never be able to "clear" it out if your fuel inlet valve, or valves is stuck open.

When you ran the sled out of gas, this left the floats in the lowest position in your carburetors, which leaves the fuel inlet valve open. Since there was no gas in those carbs in the summer, it wouldn't be surprised if a float stuck down or a fuel inlet valve is stuck open either.

Gizz --

No I shut the gas off when it was on the trailer.

Thanks for the thoughts.

A buddy of mine thinks it is a float issue as well.

thanks -- going to check that on Thursday.

      1-2" in most lakes under 100 acres with moderate depth in the north metro. Smaller lakes likely have more.    Fingers crossed the snow misses us

      Went out with my poker this morning and checked ice at Johanna. The entire lake is finally locked up and there is about an inch of ice at the end of the dock. Hopefully the snow misses us this morning and we start to build some quality ice.

      I checked numerous Aitken area lakes yesterday, 9th. The only lake where I saw any open water remaining was Cedar south of Aitken.  Ripple, Dam, Clear, Hanging Kettle, Sissabagama, Anne, Rabbit, all locked up. 2" in most places, but after last night I'm sure it added more. I would guess in the next couple days there will be walk-out traffic. There were 6 porty's on  Shakopee yesterday, and although I did not check the ice, I'd assume there is decent ice there. There were houses out there already Wed.   Be safe, use caution and common sense, and do lots of checking.

      Ice Report: Pearl Lake 4 1/2 inches on shore line. 5 inches out a couple hundred feet. 1 guy out fishing way out there.  Grand Lake 2 inches about 10 ft out from public access.

      Well from what I saw yesterday I could wet a line thru the ice today I think knot. im going to give it a week for myself personaly. but on my way to work at 3pm yesterday I looked over at the lake I mentioned was iced over since Wed. and seen two groups of 2 out in the middle of the lake ice shelters and all and 2 of them weren't that far from the aerator out there.  I just hope everyone had a good and safe day out there and no one found anything out the hard way. At best that lake caped off Tuesday night. But I predict by next weekend there will be many places to ice fish and some evan before.  Three hard strikes with the Spud Bar followed by the foot
