My carburettor is leaking oil from the gasket and the oil also appears in the airfilter tube.
What is causing this and how should I fix it? Engine works fine, without power loss and the level of oil is correct.

Thank you for your responses.

It probably comes from oil pneumothorax. For the test try to put one end of pipe to the bottle and check how much oil appears.

Fiat 126 has a tendency to throw oil out of the pneumothorax because the two pistons run together and the pressure in the engine block is high. If there is a lot of oil and it is leaking outside, check whether there is a wire strainer inside pipe in the valve cover. If there is a strainer in the cover, you need to check the piston rings by sampling the oil. I think you will find how to do it on the Internet. The correct compression pressure is at least 8 Bar, after pouring oil into the cylinder it cannot increase more than 0.5 Bar.

I installed oil catch can and It's getting oil inside.
That means the piston rings are bad? Engine works fine, without any problems.
I'll get some tools needed for the pressure test and try it.
And I think there's no wire strainer. How does it look?

Thanks!

You have photo in the link. It is to be mounted in the valve cover, in the pneumothorax connector. If this is not there, this may be the cause of your problem.
