micra k10 engine races

it has a carburettor, you will find it is a twin choke arrangement and PROBABLY the second choke is sticking open. it is a likely to be question of cleaning the carb as necessary and freeing the sticking bit. You may find that repeated spraying with wd40 and using the car hard may clear the problem

Yes, I suspected the second choke, but I've taken the carb off and its bits seem to move freely enough. Is the second choke flap opened by suction from the engine, and closed by the circular springs round the shaft? Maybe I could bodge it with an extra spring somehow?

Bodge = bad. Can't you find a carb off another similar car from a scrap yard?

If it is a vacuum secondary then it probably is just gunged up. Just make sure it all moves very freely and is clean, it should then work, extra springing would not match when it is supposed to work

My apologies for earlier post regarding "races" it was not an attempt to be funny on my part.
