The chainsaw carburetor should be cleaned according to the following algorithm:

  1. First you need to drain the remaining fuel from the fuel tank. We remove the chainsaw cover by unscrewing the fasteners. We take out the filter and disassemble the housing by removing the nuts and clips if necessary.
  2. Remove the fuel mixture supply hose from its retainer, unscrew the fasteners of the upper carburetor cover. Then we remove the top cover and the blue gasket. this is the membrane of the fuel pump. To the left of the body are the spring clamps, remove them, and then the screws. It is advisable to sign the details and schematically fix the places from which they were removed so as not to confuse anything at the time of assembly.
  3. Remove the bottom cover of the carburetor, unscrew the screw and remove the needle valve and spring under it. Then, with a longitudinal force, remove the air damper and its axis.
  4. Remove the throttle damper, drive lever and throttle axis.
  5. We lay out all the removed carburetor parts on a flat surface and conduct an inspection for integrity. Parts with a high degree of wear must be replaced with new ones.
  6. Using a specialized cleaning agent, wash the parts and dry them with a lint-free cloth. Tubes must be purged under pressure using a pump.

After all the products are dried, it is necessary to assemble the carburetor. Typically, the detergent evaporates completely in a day. It is better to wait a day after cleaning, since the remnants of detergents on the parts can get into the fuel compartment, and toxic gases will be released during combustion.

Another important nuance associated with disassembling the chainsaw is that you must extremely accurately install and adjust the needle valve petal, otherwise the chainsaw may not start. To check the correct installation of the petal, you can use the blade. Having set it on top, we look how much the petal rotates freely. If there are no problems, then everything is in order. you can continue the assembly. If stroke problems still arise, then the petal must either be crushed or an edge bent on it.
