Adjusting the Carburetor On The CS 33ET Chainsaw

Use the screw to adjust the carburetor. Idle Adjust Screw-use the screw for adjusting the amount of air during idling. Turning the screw clockwise increases the engine revolutions; turning it counterclockwise decreases the engine revolutions.

If the fuel has been in the tank unused for months, it can pick up moisture and fail to ignite. Replace it with fresh fuel. You might also need to replace the fuel filter at the same time. Check the fuel lines for cracks and replace them if necessary. If you still have problems after checking those issues, consider replacing or rebuilding the carburetor (carburetor assembly WT-949 6685209 or carburetor assembly WT-940).

For a non starting chainsaw, check for compression, remove the spark plug, press your thumb over the opening and pull the starter cord. If you don’t feel the air pushing from the cylinder, it’s likely that the piston rings need to be replaced (for an accurate compression reading, use a compression gauge).

The S-start pull-force reduction system allows for an easy start every time. The Auto Choke Return puts the choke back to running position after starting.
