I have a 2001 Sportsman 500 HO with the "normal" fuel leak from the carb bowl. I have read a lot of threads about replacing the o-rings on the float valve seat. I have my carb apart and will be in the process of replacing the rings. Two questions: 1. Can I get the o-rings by themselves somewhere other than from Polaris in a kit? (If so where and what size?) 2. My float valve seat is brass and looks like it has two rings. One is a small one that fits in a recess and the other is a very thin one that fits between the ridge and the bowl. The one that is now on there looks flat. Is the one between the bowl and the seat also an o-ring and should I replace it also? Thanks for any help. I want to get it right so I don't have to pull everything back apart again.
