I've got a three-ring gas cooker which is in need of some TLC. One large ring blows out as soon as or soon after turning it on, the other large one seems to be letting air in and will pop after it's been on a while and the flame turns orange. There's also a slight smell of gas from it which obviously isn't right or safe. The small ring is fine.

 

I'm in Somdet, which doesn't appear to have anyone who repairs anything other than electrics. Does anyone know of someone within about 50kms which includes Kalasin that might be able to sort it all out.

What I do is get a car foot pump and attach it to the rubber hose coming from gas bottle...pump and turn off on on the tap to ring ... works for me as the gas is liquid it some times conjeil.
