Default won't start

so the other day went to go start the grizz and she fired right up....ran for like a minute or so and stalled out, sometimes it does that. Then i could not get it restarted. Took out plug and replaced it, is getting spark, took out airfilter, clean as a whistle no dirt or debris in the airbox at all, i was actually shocked...but anyway i can see into carb , so i gave it a couple shots of starter fluid and she will run on that for a sec or two with each shot, so my quess is i'm starved for fuel, but why...and yes i have a full tank of gas with the petcock open, i attempted to open the bowl drain on the carb, but managed to mangle the screw head like everyone else i read about on here. I quess i'm going to have to just use a pair of pliers to drain some fuel out. any other suggestions out there. I've never had any issue like this before...it's a 2005 with less than 60 hours on it, and is stored indoors.
thanks for taking a look

Hey Grizzly, welcome to our forum. If you are like us, you have cold weather setting in. The Grizzly just does not want to start when it's cold. I'm surprised that it wouldn't keep running after the starter fluid. I assume you replaced the plug with a new one and not an old one. I found out that you can get spark from a fouled plug but it's not hot enough to fire the fuel. Has it been sitting for any length of time? If you've been riding it then your fuel and carberator is fine. You may have a tight intake valve which is not letting enough fuel into the cylinder.
Here are a couple things you can do. Clean your air filter and only use a minimal amount of oil on it. When it's cold the oil thickens up and air has a little harder time getting through. Change your oil and make sure you have a winter weight or better yet, synthetic oil. I switched to the Yami synthetic and it makes a world of differance even if it is $7 a quart. Get a Platinum or uridieum plug. You can even go one step hotter. Sorry, I don't know the numbers. If it gets real cold there like it does here, you can ask your dealer for an in-line water heater. Polaris makes one and we have them on ours and they work great. If it still won't start I would bet your valves are tight.

Like Starky said, have the valves looked at (or do it yourself if you are mechanically inclined). The Grizz is known to be hard to start when the valves are too tight.

If she fires on starter fluid then you have a spark (therefore that rules out most electrical problems). You could have a defective petcock - unlikely but possible (my buddy's Suzuki Eiger had a bad petcock after only 600km).

Grizzly welcome to the site, it could be your gas cap vent tube that is plugged? Try and blow through it and make sure it is clear? If not then take the gas cap right off and see if it will run then? Could be bad gas? Water in the gas? try the easy stuff first and go from there. Good Luck........Irv

I'm guessing if you acually get the float bowl screw open no fuel will come out. Could it be the float is stuck in the closed position? Try tapping the carb with a wrench or screwdriver- bet she frees up and then fires up.

I would be gessing no gas flow also, Shut off the petcock, remove the gas line from the carb, put a small container there to catch gas if it will flow, turn on the petcock, if gas flows, the float is probably stuck. Good thing to do if the quad only gets run once in a while is to shut off the petcock and run the carb dry, When restarting turn on the petcock then it gets a fresher shot of gas when you go to start it.

After all the crap I talked about cold weather starting I thought I better validate my ideas. Today it was -22f. When I went out to start the Grizzlies it had warmed up to -12 but was still cold as **** in the shop. With no assistance from the inline water heater, (they only work if you plug them in), both Grizzlies started right up. I chock it up to the synthetic oil. Both our machines have been hard starters in the winter but today they fired with no problem. The only differance is the oil. Here is the trick.
Close the choke. When you push the start button, only let it turn over for no more than 3 seconds. Let it site for 10 seconds then try again for 3 seconds. If you go more than 3 seconds you are flooding the engine and the spark won't ignite the fuel. This worked with our machines "today". Tomorrow may be a different story, but I'm confident that the oil is the differance. There was some knocking but not as much as in my truck this morning when I cranked it up at -22 degrees. The truck is getting the synthetic oil treatment next and then the rest of my motor driven equipment. I wonder if I can get the horse to drink a quart?

That's pretty good i must say..i will have to upgrade to the Synthetic next time i do an oil change. Although we haven't been experiencing the cold weather like you currently are, i'm sure it's comming sooner or later. I did manage to get it running, just let some gas drain from the bottom of carb, and gave it a couple taps with the end of a screwdriver seemed to do the trick. Changed plug and oilchange, not syn this time..but nextime oh and added some store and start fuel stab to all the toys this weekend. If you could send some snow our way as i'm wanting to go play.
