I have a Cannon Salisbury and only 2 of the hobs are working (the two front ones). I think it is the gas valves controled by the knobs as there is not enough gas coming out when you switch it on and you can't light it with a match but obviously the other 2 are fine. There is something coming out when you switch them on but not enough For a while one of them was working but the flame was very small, even on full but then it packed up.
Any ideas on how to repair it?

I doubt very much if the taps are blocked so not allowing gas through the hobs.Check that the bayonet in the wall hasnt started to come out of the socket as this could cause low pressure.Make sure if it has a drop down lid that it is up straight as this can cause problems also.
