Last sunday my carbs started flooding out and peeing gas. So I took them apart and cleand them, they didn't have any dirt in them anyway. So today I was driving around and for 15 minutes or so it was good. I was crossing a lake and all of a sudden it just starts bogging out and peeing gas out the vent lines. Any ideas on what else to look for?

Torn pump diaphragm, sticking floats in the carb.

saturated floats that need replacing.

I poured some gas line antifreeze in and it ran good all day. I went in a couple drag races. I blew away a RMK 700 a xc 500 and a fusion 600. Made me feel pretty good.

You may have ice in the bowls also. Drain the carb bowls.

Already did. I ran it again today and no problems except the starter rope breaking lol.

Could have some water in the tank? Try taking the carbs apart pulling all the jets and soaking them in a carb cleaner over night. Then clean them real good and blow them out. Replace the needle and seats and try again. You need to be very carefull a spec of dust you can barely or not even see can lean down an engine and toast it! If it runs better than it ever has turn off the key and park it, it's about to blow!
