Useful information:

On a two-stroke engine with carburetor, it is imperative that the carburetion setting is always adapted to the ambient temperature as well as to the altitude for optimal performance.
You will find in our shop everything you need to adjust your PWK carburetor.

A rough-finished muffler needs to be maintained. Remember to coat it with oil or degreaser after each cleaning so that it does not rust.
