A neighbour of mine (female) has a 10 year old PP, it's having spells where the
ignition sparks every second and you can see the flame size cycling up and down
at the same time. From a thread in 2001 it could be a break in the spark lead.
However their local corgi guy is talking about a failed gas valve but
apparently he doesn't really inspire confidence. If it were mine I would have a
play, but I can see this repair getting expensive, say if the guy replaces the
valve and then the board. My gut feel is that if they can't do a "cheap" fix
she should consider a replacement boiler. Or am I being unfair to Potterton?

I'd be bl**dy wary about mending Gas appliances for neighbours. Wont you
be at risk of "it was OK and didn't do something else wrong before you
touched it" and all that sorta stuff?. Apart from if anything should go
wrong otherwise.

Apart from the fabled Potterton electronics:-(...
