hi guys welcome to another video about mild slidin today that's how to do a video on how to start a flooded snowmobile so if you're new to snowmobiling like I am something that's gonna happen so especially if you have a slide like this with a primer on it when a snowmobile is cold it needs more fuel or a richer mixture to start than when it's an operating temperature so what happened a lot of times what I did was I would use the primer either when the sled it was a warm when I was getting used to things or I give it too many shots on the primer ended up flooding it so there's so much fuel in the cylinder that the spark plug actually can't ignite it um so if you're you know you've been out riding and it has been running good but then when you go to start it you can't get it started and you smell gas or you've got gas coming out of the exhaust then you probably flood it so typically with a flooded engine what you would do is you would just sit and when you you give it enough time that gas evaporating go ahead and start it with a snowmobile out though you're quite often gonna be on the trail early in the cold and you don't want to sit around like that so show you a quick trip trick for getting your sled started we're gonna take these spark plugs out so what we want to do is clear the excess fuel out of these cylinders so you gonna begin by taking your spark plugs out so when it's flooded you're going to notice that your spark plugs are wet with gas so you're gonna carefully dry them off okay now we want to clear that excess fuel out of the cylinder so what we're gonna do firstly make sure your emergency stop is off you want any spark why are you doing this just pull it on the throttle open pull it now because the spark plugs in there you're not dealing with any compression so this would be really easy and you might do this 15 20 times make sure you get everything out of those cylinders there you go you're up and running again so it's fairly easy that's how you clear a flooded snowmobile engine so again it's fairly easily done with with the primers on these sleds so you want two or three Prime's once you feel it squishy once the gas is in the line and just be careful not to over use it and once it's warm you shouldn't need to prime it at all so try starting at first before you prime it you can't get it started then give it a shot or two but you know if he's just once it's warm if you go ahead and give it two or three Prime's that's enough to flood it okay so hopefully you found that helpful if you did go ahead and hit subscribe and I'll see you next time

    I’m a rookie snowmobiler (recently bought a 2001 MXZ 440) and this video saved me today!! I don’t seem to have any issues starting from cold but once I ride for a while and let it sit (30-45mins) it’s the restarting that is giving me grief. Like today after the sled sat for a while I choked it and it briefly started but died. Then I give it one prime and couldn’t start it. I must have flooded it. Did the trick you showed in this vid and it fired up! Thanks!

    Thanks for letting me know about this. Glad I didn’t have to search around too much to find out why my sled won’t start. I did use way too much primer. Probably about 30 uses of the primer.

    At times, you can get away by just holding the throttle wide open allowing more air to lean out the mixture and to aid in evaporating excessive fuel. However, once a spark plug(s) are soaked with fuel, they will have to be removed and dried thoroughly for them to ignite properly.
    Thank you for the video..following your procedures will surely get that machine back on the trails.

    I definitely prefer a choke over a primer.

    Do not use a rag to dry your spark plugs. The gap on spark plugs is sensitive, and if you dry it wrong, you will mess it up (it can be regapped, but not without a cheap tool that you probably don't have in your snowmobile bag). Just take the plugs out, and either blow on them or just set them off to the side. The gas will quickly evaporate due to the now high exposure to air, and your gap doesn't get knackered.

    You could always just hold the throttle wide open and pull it over. Usually only takes 5 or six pulls.

    take spark plugs out put your plugs back in spark plug caps place them over the cylinder hole leave kill switch on and pull burns up all excess gas in cylinders then heat your spark plugs up with a lighter put back in good to go. Saves alot of time

    Good vids and good tips man. I just bought a 99 formula triple 700. Goes like stink. I find sleds are particularly easy to repair, but sometimes you get that odd problem that requires in depth effort lol. I subscribed by the way

    nice sled my boss had a 96 ski-doo mxz 670 just like that he let me use it for a whole winter and I had a blast it brought back memories of when I had my sled I had a 81 Artic cat 4000 440 jag and I surprised a lot of people with it they always underestimate it because it was a older 440 but I showed them that it was still fast and I could keep up with all the 600' Thur the mid 90's and early 2000's my little only 440 would even walk off on some of the 600's I am about to be buying a 76 Artic cat panther 440 that is in mint condition just needs the carbs cleaned and a 81 Artic cat trail sled 340 mint condition just needs a primary clutch I am buying the pair of them together for 150$ and with all the parts sleds my uncle has I'll have a primary clutch on the 340 and have my 440 and my wife's 340 on the trails when it is time to ride snowmobiles

    My ext 580 is behind a shed under a tarp froze to the ground facing a fence with the rear end held up by a big brick. sigggghhhhhh It also needs an oil change, new plugs and carbs clean and also new gas… The sled is in nice condition though.

    Personally I'm not crazy about sticking the throttle open, and I've also found once its flooded, I can pull my arm off and it takes a long time to clear the cylinders. Doesn't happen much now I'm used to it. No, I find my machine starts in one pull once its warm.

    Dude what I did is put a black plastic tie wrap around the gas throttle in WOT and I can use both of my hands to pull on the cord… Then i just slide it off… I leave it there if it ever happens again…

    Does your machine when warm get finicky when it's time to start ? When I drive it for about half an hour and stop at the gas station time to put fuel till full, go in and pay and come out… I go to start it and it won't start with giving it abit of gas… Weird thing…
