I have a 1997 Polaris XLT and for some reason its hard to start my dad and brother say its flooding and it wont start unless you just had it started less than 30mins ago and one time i went trail riding we stopped at this one place and we came back about 45mins later and i was in a group of 5 or 6 and they all started there snowmobiles in one pull but i had to pull mine a bunch of times until it started but i don't think it should be that hard to start. any reason its so hard to start? thanks.
