There should be a stamp on the cylinder somewhere that says how many ccs

Have you got any recommendations on how to tune the carburettor?

It should be a round slide carburetor. You can go on YouTube and find some pretty good explanations on tuning

All carburetors have 3 basic settings:

max rpm no load full throttle;

slightly under max rpm no load, no throttle favoring the rich side;

idle setting.

As to how these adjustments are made, that can vary depending on the carburetor.
