How do you adjust carb on 330evl echo chainsaw?

Answer 1

To adjust the carburetor on a 330EVL Echo chainsaw, start by locating the adjustment screws marked "L" (low speed) and "H" (high speed). Use a screwdriver to turn the "L" screw clockwise to lean the mixture or counterclockwise to enrich it, usually adjusting it while the chainsaw is idling. For the "H" screw, adjust similarly while the saw is under load, ensuring it runs smoothly without stalling or excessive revving. Always refer to the user manual for specific settings and ensure proper safety precautions are taken.
