DATR conversion to electric choke?

How about this?

Thanks for that. I think I've gone down the wrong rabbit hole.

My car runs and pulls well, however the MOT garage adjusted the carb to keep emissions in the acceptable range. For me, it's now idling a bit too low and it has on odd occasions stalled. If you look at the picture the screw boxed in green has always been missing so nothing engages with the stepped cam. I had this idea that an electric choke would do away with that issue, but I don't think it does.

Reluctant to touch the mixture screw and introduce more variables so I was going to keep the idle a bit higher using the red screw.

As you can tell I have basic to mediocre understanding, but I'm not after fuel efficiency, max performance, just a reliable car that I can trust not to stall at lights.

John,

You can safely turn the mixture screw anticlockwise to richen the mixture.
I'd suggest a half turn first, then road test. Repeat until it feels better but not more than
2 full turns. It should get progressively better.

That missing choke screw should be available from one of the weber dealers.
Your cold starts would improve.

ps, I hope the mot guy was using the 4.5 max benchmark
and not the later lower figures.

that missing screw would really make a big difference when cold.  I think I have seen details on how it should be set up, I think its on the third step.  I bet your choke will then be fine
