They're new and seating fine. The float was bent (presumably a backyard fix by the former owner) and you have to bend it so far down that it would risk stalling out on big dunes. That's why I thing it'd be easier just to go new carb. Thanks for the info guys I'll be on Amazon tonight.

I'd bet you got stuff stuck in the needle/seat area.

Every time we've been riding and someone is just flowing gas from their over flow this is exactly the issue.

Piece of hose, dirt, rock, some other debris is stuck in there and won't allow it to close and shut off the fuel flow.

1) Take and carb apart.
2) Take the bowl off
3) Take the main out of the bottom
4) Remove the plastic circle retaining ring
5) Remove the pin & float adjustment tab
6) When this comes out the needle should be hanging on the center of the float adjustment.
7) check for debris under the float needle and where it seats.
