Carburetor adjustment.

On chainsaws Huter BS 45 and Huter BS 52 a membrane carburetor is installed with the ability to adjust the quality and quantity of the mixture. After purchasing the tool, it is recommended to slightly enrich the fuel mixture in order to compensate for the loads that occur during the piston lapping process.


After the saw has worked on the enriched mixture, and the parts of the piston group will rub together, the quality of the mixture should be normalized.
For the quality of the fuel mixture is responsible for the screw (L). The screw must be turned a quarter of a turn counterclockwise to enrich the fuel mixture (increasing the fuel supply to the cylinder) after running back to its original position.

If the carburetor of the saw is completely deregulated, its adjustment is carried out according to the following algorithm:

  • on a dead saw, the screws L and H are set 2.5 turns from the fully twisted state;
  • the saw starts and warms up within 5-10 minutes;
  • after warming up, slowly tightening the screw L, it is necessary to find the maximum speed at idle, and then release the screw to a quarter ode;
  • screw H regulates engine operation at maximum speed;
  • after adjusting the screws L and H, adjust the idling with the screw T. It must be set in such a way that the engine runs stably and the chain does not rotate.


Adjusting the maximum speed should be done using a tachometer. If there is no such device, then the screw is tightened until the moment when the engine starts to work smoothly and monotonously, easily gaining momentum.
It is worth remembering that the adjustment of the carburetor should be carried out only after the complete diagnostics of the saw has been carried out, and such faults have been eliminated, such as depressurization of the crankcase, air leakage under the candle, and gasket of the carburetor.
