Setting up a factory carburetor Champion chainsaw is necessary in several cases.

Their list includes:

  • wear or defect in the engine’s CPG;
  • a sharp increase in vibration of the motor;
  • arbitrary engine shutdown;
  • increased fuel consumption and increased volumes of exhaust gases;
  • carb blockage.

The instructions for using the model will tell you how to independently configure a malfunctioning saw carburetor. The correct course of action, in any case, should look like this:

  1. First, on a chainsaw with a cold engine, all the adjusting screws in its device will need to be returned to its original position. It is indicated in the garden tool manual;
  2. Then you need to start the saw motor and wait until it warms up;
  3. Next, you will need to start turning the screw L in different directions until the optimum low engine speeds are found. Immediately after this, the bolt L must be turned a quarter of a turn in the opposite direction;
  4. According to the same principle, it is necessary to carry out adjustment with screw H, which will allow you to find and set the highest possible engine speeds. To more accurately determine the speed of rotation of the motor at acceptable speeds, a tachometer will need to be connected to it. Then you need to start slowly turning screw H. As soon as the revolutions on the tachometer and in the instruction manual for the Champion saw match, the screw must be released;
  5. If after setting, when the saw is idling, the chain rotates on the tire, it means that you need to turn the bolt T in different directions one by one until the chain stops.

After completing the adjustment of the carburetor of the saw with your own hands, you need to check the operation of the fuel unit. If the chainsaw is steadily gaining momentum, its engine is running stably, and the chain does not rotate along the tire at idle of the engine, which means that the adjustment was performed correctly.
