How do you get a snowmobile started if it runs out of gas?

What kind of snowmobile??Usually you put gas back in it..If it has not been running for atleast an hour then full choke & pull til it fires..At that point when it fires you can turn the choke of & it should go..Itmight take a few pulls to get it to go & try not to flood it otherwise you can pull &pull but it will never start..If it floods,take out the spark plugs & dry them & heat them or just put in a new set..
