Hello! Sorry for the late reply, but just now found time to install the new carburettor due to a cold weather. Installation was relatively easy. The engine started on the second try. I have to adjust the carburetor for idle operation with a gas analyzer. For now, purely subjectively, I think the engine feels more responsive. I haven't driven the car much since the installation of the new carburettor and so far I can't share my impressions about the fuel consumption. I am sending to you two videos of cold engine running and warm engine running (still not completely adjusted). Thank you very much!
