If the air filter is clogged, do not hesitate, change it. It only costs a few euros.

Remove the air filter housing
Op 01
Unscrew the 2 wing nuts securing the air filter housing. Unscrew simply by hand or use the multigrip pliers.
Recover the flat washers and seals.
Op 02
Remove the air filter housing. Pull with your hand.
Once the air filter is removed, it is best to block the carburetor elbow with a cloth to prevent the entry of any impurities (3rd photo).
Change the filter cartridge
Op 03
Remove the air filter cover. Use a large flathead screwdriver.
There are slots between the filter housing and its cover in which to engage the screwdriver.

Discard the filter.
Op 05
Thoroughly clean the air filter housing and its cover.

The air filter sometimes arrives packaged in a rectangular cardboard box. This is not a problem because the filter is very flexible. It will very easily return to a cylindrical shape and be able to be mounted in the housing.
Op 07
Fit the cover on the air filter housing.
The arrow engraved on the cover must be oriented towards the air inlet (2nd photo).
The notch on the cover located to the right of the arrow must be perfectly positioned above the boss of the housing (3rd photo).

Close the air filter cover. Press firmly by hand.
Make sure that the cover is properly clipped on all its periphery.
