Oval throttle valve C15

[Sage29]

I've just stripped my carburettor down on my 1961 C15 and noticed that there is play between the throttle valve and carburettor body, upon further inspection I've measured the throttle valve and it is oval I'm guessing due to wear, there is also a score in the carburettor body, do I need to replace the carburettor or will it still be ok to reassemble and use?
Any advice appreciated.

Sounds like a new or a better used carb would be best option.

Give it a try first. It may be acceptable with the worn carb, after all, that was what it last ran with.

I rebuilt a Bantam and a C15.
Both would run perfectly one day, then refused to start for the next week.
For each one I 'bit the bullet' and bought new carbs - instant success!
