The AD Chummy has an updraft T24 Carburettor. I have stripped it & cleaned the muck out, checked the jets are the recommended ones & put it back on with a new gasket. The car started well, but will only run with the choke fully out!
It will rev a bit and even tick over like this, but this is not a good long term plan!
No clouds of petrol-ly smoke, sounds quite healthy, but something is clearly wrong somewhere.
Took the carb off again to see if the slow running jet was blocked, but no: clear.
Put it back together, same result.
Mixture screw 1 1/2 turns out from fully in.
What next to try?
Previous owner said it ran earlier this year, but it may have been like this!
