Blocked gas jet

[PaulSB]

Three of the rings on our gas cooker are working perfectly, the fourth will not light using either the ignition button or a naked flame. I'm sure no as is coming through the jet. When I removed the burner I found debris and water in the well surrounding the jet and feel it's likely either water, debris or both have got into the jet.

The jet looks to be removeable with a small spanner. Is this safe to do? I presume the gas flow is governed by the on/off dial and not the jet. If I try pushing a pin in to clear debris this might worsen things by pushing debris in further?

Any thoughts?

Could also stick a pin down the jet and make sure the burner parts are all clean.

A pin is way too big for a gas jet. A piece of wire such as that from an electrical lead. One strand, rolled flat, should be small enough. And it'll be softer than the material the gas jet is made from.
I'd go no further than this, unless I had a spare jet to hand.

Is the area around the jet now clear of any debris? You can remove the jet, 6mm is a common size, but bear in mind you may have to seal it again when replacing it. Some are tapered to get around sealing them with anything.

Turn the gas off at the meter before pissing around with anything!
Id probably not start unless I had a new jet to hand incase I needed it.*
