Let it dry and added dielectric grease. I then tested for spark again and presto I've got spark!! I've had the gas shut off while I was testing and could not get it to start. I does fire right up if I put carb cleaner in the spark plug holes. So now I just have to get the gas back to the carbs. If I can't I'll pull the carbs off again and clean them and check the gas lines. How many pulls with full choke do you think it should take if I've had the gas? off?

That's very encouraging news at a minimum.

Choke doesn't really have any bearing on filling the bowls - it's all about getting the motor turning to run the pump - that's what fills them. The choke only determines whether or not -additional- fuel will be drawn from the carbs, but they have to have fuel in them in the first place.

If you have a syringe, you could pull the fuel line off of each carb, draw up some gas into the syringe, and then squirt it into the carb through the fuel line nipple. Do this to each one, replace the fuel lines, and you should be up and running more quickly.

Squirt a little oil directly into the plug holes before you start (not too much) to help keep the cylinders sliding smooth while you're pulling it over.

Great I'll try it today and see how it goes!

Not sure if this will help but what i did to fill the carbs after i pulled them out to clean them was, i had the kill switch off, gas on and took the plugs out ( i have a triple so i didnt wanna deal with compression) and i pulled it a few times until i saw fuel go into the carbs. Put the plugs in, kill switch on and it fired right up first pull. Hopefully thats another easy way.

Out of the frying pan and into the fire!! Well I tried the things you guys suggested. Nothing worked. So I pulled the carbs and wasn't getting gas to the carbs. Before pulling the fuel pump I pulled the line off from the gas tank itself (before the gas shut off valve). I am not getting any gas here. I tried siphoning with a pump but that yielded no gas. Is there a one way valve in the tank or something I'm missing or is this line clogged somehow???

meburdick · 01-15-2013, 12:56 PM

The pickup line may have fallen off inside the tank (check your fuel level to see if it's up high enough and/or try fishing the line out of the tank with a hanger).

Camlee98 · 01-15-2013, 03:42 PM

So the fuel should free flow from the line before the shut off valve correct?
If the pick up line has come off then I'll have to drain the tank and put it back on?
Do I do that by removing the petcock assemble the pickup line and put back together?
I see how to take the tank off but how do I get the seat off? I didn't see any bolts for that.
Is it easier to remove the oil tank and do it that way?
Will I ever get to ride this thing LOL?
Thanks again for sticking with me and helping me thru this!

meburdick · 01-15-2013, 04:00 PM

It probably won't flow completely freely, but it should come out if you can pressurize the tank (plug the fill hole with a rag and put the hose of a compressor in there).

Sometimes that line falls off, sometimes it rots off (thanks ethanol...). Either way, the process is the same. You need to pull the seat back so you can pull the tank (check the Polaris parts fiche for information on where the bolts are and such). You pull the hose off of the outside of the tank and there's a connector that will unscrew from the tank. On the inside of the tank side of that connector would be the hose that is in the tank. That hose is held to the inside of the connector with a special clip. Special clip means special tool. If you don't have that tool, you might need to get special gas line that won't require that clip to stay in place.

Oh good grief!!! Looks like I have more work ahead of me LOL!
I think I only have a couple gallons of gas in there so it could be that I don't have enough to cover the broken line (if it is broken). Looking at the parts diagram it appears that the compression fitting is the same a the pex stuff. I do have a pex crimping tool. I would still need the fuel line. I guess I'll cross that bridge when I get to it.

meburdick · 01-15-2013, 06:11 PM

Fuel line is fuel line is fuel line... Don't think that will be an issue.

Open up the filler hole and fish a bent coat hanger in there. See if you can get it to grab the line and pull it up through the filler hole. At a minimum, you should be able to tell whether it's still connected to the fitting or not.

Also, if you pull the outlet line off of the tank and pressurize the tank a bit, do you hear air hissing out of the fitting?

Camlee98 · 01-15-2013, 07:29 PM

Looks like 2 to 4 inches of snow tomorrow. Maybe I won't be out there working on the sled LOL Oh well!

meburdick · 01-15-2013, 08:36 PM

Tomorrow? No. You need to be out there tonight!

Camlee98 · 01-15-2013, 09:41 PM

I'm at work till 11:30 tonight.....That's all I need is to be pulling off a gas tank in the middle of the night lol

Yes that is what I've been using when I can't find where a part is located.
2 to 3 inches of the white stuff today. So I'll go out and fish for the gas filter tomorrow. If it's broken I'll go to one of the local polaris dealers and get everything for the inside of the tank. Maybe I can talk them into putting it together for me.

meburdick · 01-16-2013, 08:29 PM

"Everything" should consist of the line and a screen (filter). If you bring in the fitting, maybe they'll clip it for you. Definitely wouldn't hurt to ask.

Camlee98 · 01-17-2013, 03:42 PM

I did not have a chance to go fishing for the line today but I was close to the polaris shop. So I picked up a new filter, grommet (was told there was a good chance of it leaking after being removed) and about 4 ft of fuel line. The guy told me the fuel line is ethanol resistant and the clips inside the tank are just clamps so they shouldn't be a big deal to put on. I'll see if I can knock that out tomorrow and change all fuel lines while I'm at it.

Camlee98 · 01-18-2013, 04:40 PM

I did very little work on the sled today. It was a whopping 17 degrees and I wasn't into it lol. I did manage to fish that line out of the tank. It was still attached but that doesn't mean it's not broken at the tank side. There was a small slit/crack in the line near the filter so I cut the filter off and replaced it with the new one. I'll check tomorrow and see if I'm getting gas thru the line. I may just pull the tank anyway and replace the line inside. I have the new gas line so I might as well. I'm going to replace all the lines under the hood anyway.

Camlee98 · 01-19-2013, 04:30 PM

Ok I pulled the tank today. It wasn't as bad as I thought. It was kinda easy! I pulled the inline filter and line out and this is what I found.

As you can see that was a problem. That was on the tank side not filter side. So if I would have had enough gas I would have never known about that.
Got it all put back together with all new gas lines inside and out. After a little priming boom back up and running!!!!!!
Thank you for all your help!!!!!!

meburdick · 01-19-2013, 04:33 PM

Sounds like you're in great shape now... Good job.

Unfortunately, those lines will crack or break right off and he symptoms are just like you described. The "worst" part is that you can't get your sled to use the full tank of gas, and you could end up in a situation where you strand yourself on the trail.

Glad you got it squared away!

Camlee98 · 01-21-2013, 03:31 PM

Thanks I couldn't have done it without you!!
