My pilot light flame has gotten too big, it does past the two
sensors. I found the adjustment screw on the honeywell valve, but
the flame does not respond to the adjustment. I tried unscrewing it
all the way (using a very small flat screw driver) to see if the
spring is stuck, but there is no spring. My stove is a Vermont
casting stove about 6 years old. Any ideas? Also, curious what made
the pilot light get bigger to begin with? thanks
here is a picture of the gas valve.

Your gas pressure may be too high. I had a guy from our local gas
company tell me that most of the regulators are set to 6-8 inches
water column pressure. You will find some homes with a main regulator
set to 2psi with a separate regulator on each appliance. You should
find out what you gas supply pressure is. Most of the time, when
the gas pressure is too high, the gas valve is designed to lock out.
If you know what a manometer is and how to use it, you could find
out for yourself but it may be best to ask your local gas company
if they'll check it for you. I'm assuming you're on natural gas.
What about the other two adjustment screws I see. Do they affect the
pilot light or just the main flame? If pressure is the problem, why
was the pilot size fine until now? I forgot to turn off the pilot
light during the summer, is that bad for the pilot? I did have a
small gas leak at the valve connection, so I tightened it, so it's
fine now. Maybe the high pressure can cause a leak?
Also, what about main shut off valve out side the house. Could I
open it only half way to reduce the pressure?
Its pretty obvious that you don't know what your doing, and don't have the
proper tools to do it.....
Best to do like you were told.... call the gas company and let them do it.
Home owners messing with gas appliances that they really don't know anything
about, can have serious consequences.
Well, you got good advice and no one is trying to be arrogant
or snooty. I hate to see ANYONE get hurt because they don't
know what they're doing with something as dangerous as natural
gas. If you have the large diameter gas lines, 3/4 inch minimum,
you have a low pressure system where the pressure of the gas
will feel like you are blowing on the back of your hand, you may
not hear a leak like you would in a 2psi system. If you smell
the mercaptan, you're in danger. The odorant was adopted many
years ago because so many people had been hurt or killed because
of fires and explosions due to gas leaks. Please, please, call
your gas company or heating and air service company. Those folks
will have the knowledge and proper test equipment to diagnose
your problem. If you don't pester them too much, they let you
watch and explain what they're doing.
Sure looks like the "PILOT ADJ" to me.
As to the main gas valve, closing it half way won't affect your pilot.
However, when your furnace or water heater tries to run, it may
starve for gas. I'd leave the gas main valve wide open.
Maybe your gas company or a HVAC guy can check your gas pressure. See
if the house regulator is delivering too much pressure.
Dang! I just had a thought, I wonder if the screw is actually a plug?
You have to take the screw out to reach a needle valve inside the
opening. I've never seen a Phillips head screw as a plug, it's usually
an Allen socket plug.
