1966 Cannon A134 D/2 gas cooker oven overheating

Hi. First off, I registered just to ask this question, after Googling and finding the closest match here (I can't post the URL link, but it shows as Vintage Cannon Cooker Restoration). So hope this is the right place.

I'm trying to find out if it is possible to fix a 1966 Cannon A134 D/2 gas oven that is overheating. Basically not throttling back when gets to selected temperature. The gas mark dial was consistent if a little out up until last year. It is usually used at gas 5. Then, after a gas 8 cook the temperature accuracy shifted out a little, with the dial needing to be down to maybe 4.5 where it used to be 5. This last week though, when set to 5 it didn't stop heating up / throttling back. As far as I know, it went full blast to 8 or higher for the whole cook. Pulling down to 3 and a bit I believe quietened the flame but only temporarily.

I assume that, if anyone can advise, you'll need photos but I'm not sure what to photograph. Inside the oven there are 3 holes at the rear base, one for the burner the other 2 not sure. There is also a small hole front right base which apparently is a way to light the oven using a match.

Anyway, I appreciate any advice.

You need a gsr in to look at your cooker. We cannot and will not give advice on the installation or repair of cookers for your own safety.
