Moose racing carb kits

[flatbedin]

My left carb started pouring gas out of the overflow this weekend, so I pulled the bowl and checked for trash on the tip and seat. Carb was spotless. Removed the seat and checked the o-ring. Reassembled and it still leaked. 2nd time disassembling I noticed a groove (ring) worn around the rubber needle seat. These needles and seats are about a year old. Went thru my carb parts and found the best needle out of 4 used ones (all Moose). The leak stopped, but why are these needles only lasting a year? The quad sits most of the summer and is ridden most weekends in the winter. I never drain the bowls. Should I? Could it be something in the gas not compatible with the rubber needle? Something in the 927 oil? Can I get better quality needle?

Yeah, drain the bowls when it sits. Leaving the floats full of fuel, will keep pressure on that little rubber "cone", creating the groove. It's an easy fix, and easily prevented... Just let it idle, and run itself out of gas.
