The New World seventy-six cooker I have needs the taps / knobs
lubricating - I saw something on a previous post suggesting gss cock
grease. Is this the stuff, and is it straightforward to dismantle and
re-grease them? A gas engineer I spoke to muttered darkly about carbon
monoxide and said any engineer would charge £100 to come out and then
slap a condemned label on it to cover himself. I like the cooker but
like life more - should I think of scrapping it for safety? The flame
on one burner was a little yellow, to I closed what I took to be an
air inlet screw on the cast iron pipe leading to it - this improved it
but even fully tightened the flame is still a little yellow. Would re-
greasing the taps help this - and should I be in there at all? Thanks
for advice.

Greasing gas taps is relatively simple, do not use excessive amounts
of grease or you may clog the injector and bypass ports. As with all
such jobs you really ought to have the facility to check the cock is
closing of correctly and does not leak around the barrel on completion
(a little leak detector spray might be a reassurance here) With
respect to the yellow flame, a thorough clean out of the air inlet,
burner mixing tube and the burner head may work wonders. Your screw
adjustment needs a bit more clarification. Is it a screw which
projects into the mixing tube? If so the effect of screwing it in is
to create a resistance to the flow of gas and air from the injector
jet to the burner and would tend to soften the flame by reducing the
airflow. Less air, same amount of gas will tend to cause yellowing of
the flame not reduce it. On an old burner scaling and corrosion may be
causing a restriction within the casting. Try a stiff baby bottle
brush or similar

Thanks for all that. I will see if I can get hold of some gas cock
grease and give it a go...What I described as 'adjusting screws' are
located on the top of the mixing tubes, just behind the taps. I'd
assumed they were to adjust the gas / air mix, but from what you are
saying that is not really correct. I am wondering what their purpose
is? I will start with a thorough clean as you suggest and go from
there.

My biggest concern is the yellow flame. It is indicative of a incorrect
air/gas mixture. If you've opened the air inlet screw wide open, the next
thing you can look at is the burner. I guess it's made of cast iron in
which case you'll probably find rust has closed the gaps to restrict the
flow of mixture leaving the burner. The offending burners should be removed
and the slots cleared. You might also find the slots are coated with dried
household cleaners.

I'm sure some here would frown, but generally if you have a blue flame,
you've got complete combustion with little or no carbon monoxide being
generated.

Flame failure device, in the oven at least and increasingly nowadays on
the burners too (mandatory in blocks of flats).

Plus taps and regulators that are designed for higher pressure NG (aka
North Sea gas) rather than ancient Town Gas.

Thanks for confirming what I thought about flame failure devices.

However the taps and regulators must have been acceptable at NG
pressures when the conversion was done. (Would the regulator have been
changed at conversion time? If so, then it would even be designed for NG.)

Not an issue as it has been converted. The taps themselves were rarely and
issue when converting appliances.

Nah, they simply left the old taps in place so you had to carefully
manipulate these through about a quarter of their full travel to control
burner flames under the higher pressure NG.

Age, of itself, doesn't make something dangerous, does it? OK - maybe
some materials have deteriorated, some wear has occurred, it might not
have all possible the safety features we expect, but if it has worked
for 50 years without (we assume) killing anyone, is it really more
likely to kill someone tomorrow than on the day it was first installed?

If it is like the old New World cooker I had, the biggest issue I can
think of is lack of any flame failure mechanism. But its extremely solid
build was a plus.

Yes it's really well made. Is flame failure cut-out now standard?
Never come across it.. My safety concerns are to do with the age of
the thing, but although not an expert I don't usually think of age as
bad (increasingly so!); just depends on the context. Call me old
fashioned but mountains of recently manufactured stuff being dumped to
be replaced ad infinitum doesn't seem to make sense...

Truth to tell, I just *assumed* that some such would be fitted to the

realised that I don't know - hopefully someone who does know will now post.

No, flame failure is rare on hobs. That's why 22mm pipe is used for gas
nowadays, when a big boiler kicks in, it could suck up enough of the gas
in a pipe, that a lit burner on a hob temporarily goes out as gas flow
is reduced so much, the gas flow would resume fairly quickly, but it
wouldnt be lit.
Separate gas pipes to the cooker and boiler usually solve this, as well
as the bigger bore pipes now required on boilers.

Use graphite grease. Remove the barrel and clean with a light wire wool.
Look inside tap housing and clean off any accumulated crud.

There is a New world cooker in a flat a couple of doors away. It is in
better health than me and about the same age. I usually get to the do
the Landlords' inspection. I am determined to keep this appliance in safe
working order.

Clearly the oven let alone any other burners don't have flame failure,
therefore the cooker is "not to current standards"! (Frankly it's better
than a notionally compliant brand new "B*ko" from C*met et sim.).

A few years ago I did re-grease all the taps using a tiny amount of gas
cock grease. More recently I repainted the numbers on the Regulo. I did
remove the mini gas poker from the side a few years ago. Peizo or Piezo-
gas lighters weren't widely available when it was made and there were a
lot of ways that gadget could make trouble.

If you have yellow tinged flames on any of the burners then you will need
to eliminate the problem.
Jet worn? Jet blocked? Mixing tube dirty inside? Aeration settings wrong?
Holes in burner (especially over) partly blocked? Wrong gas pressure.
If in doubt get an experienced pro.

However the only parts that can wear out are the Regulo, the injectors

The gas cocks are serviceable with care.
The injectors should be replaceable but the only reason would be if the

The Regulo would be game-over though.
