These are the signs of the mixture being too rich; too much petrol is flowing into the engine. You need to find the mixture screw and turn it into the carburettor body. This will reduce the amount of petrol mixed with the air, making the car run better and the plugs should be cleaner after a long run.

Should I close it all the way?

You mean that one?

That looks like it. G-E-N-T-L-Y screw it in until it is fully in-DON'T force it! Now unscrew it about 2 to 2 & 1/2 turns and then start the car and then let it warm up first.

When it's warm use the tick-over (idle) screw to speed up the engine a little. Now drew the mixture screw in and out a little to obtain the smoothest running and then turn the tick-over (idle) screw down to reduce the tick-over to the correct level.

This is just a quick method. The carburettor was probably supplied with a set of tuning instructions.

Thank you very much I will try it and let you know if it helped

What engine do you have, and what is the carburettor type? (the two digits after "32DIR", stamped near the mixture screw).

I have 1100 engine and the carburettor is 32dir56

Good evening I am looking at your red silicon hoses Is your R4 LHD or RHD I need the Bottom rad hose in red for a RHD R4

This carburettor was an original fitment for R5TS (bigger engine and hotter camshaft than the 1100). No doubt jetting is incorrect. It will be rather challenging to set it correctly and it has to be measured with an AFR reader throughout the rev / power range.

Thank you very much for your reply.
Do you know what jets I need to change? Maybe I can buy some jets and try different set up

Had such a carburettor been officially fitted on a 1100 engine, you could "copy" the factory jetting to have a point to start with.
I can't guess which jets need to be changed without measuring AFR on the road or on a dyno.
