Does it have to be plugged?

I have a question on the 650L carb. Look at the picture and tell me please if I have to plug this hole.

No, do not plug as the picture indicates. It is the decelerating richening circuit, some call it the anti-backfire valve. It will run with it being plugged as normal until you let off of the throttle then it will tend to backfire more as the circuit cannot be activated to add a little more fuel. Very brief discription and I hope this helps.

Leave the hose as you have described.

Thanks a lot guys!! I just finished cleaning my carb and this pic saw on the net got me thinking! I'll leave it the way it is ...

Thanks a lot!
