Did you get to the bottom of this?

Sorry for the late reply,

I drilled a bigger hole in the jets under the ring, my drill bit was big so it let's a lot of gas through and burns white ( too much oxygen ) the Mrs won't use it on her own so I now need to source new jets.

why on earth would you drill through the jets!? mental.

Good grief.Why take a drill to the jets.Shame we don't have the axle nut award any more,you would win hands down.

^^^^^ That's the one I needed!

Never made any mistakes? Good way of learning if you survive.

Drilling out the jets was a mistake, posting about it was a bigger one!

Hang on folks, aren’t you all missing something.

Surely If you drilled the gas jets larger, as you say, and now too much gas is coming out, that would make it burn rich, with a yellowy flame (not white) because of too little oxygen?

If after drilling the gas jets out, it is burning lean (white hot flame) then there certainly must be summat wrong further "up-stream".

You won't get a white flame running lean, white/yellow flames (like a candle) are caused by the glow of tiny soot particles which are heated to incandescence and imply not enough oxygen for complete combustion.

To confirm my thoughts on this I looked at this =

And in conjunction with that:-

Flame is white-blue and has hard, sharp features. Possible Cause = Excessive primary air.
Flame is small and blue in colour. Possible Cause = Clogged burner orifice / Clogged venturi / Restricted or clogged gas line / Low gas pressure.
Flame is yellow. Possible Cause = Insufficient primary air / Blocked primary air shutter / Oversized burner orifice.

I am in no way an expert on this though, just going on my "rough knowledge"
