  • Unscrew the accelerator pump screw and pull it out. Then unscrew the fuel transition jigger of the secondary chamber and remove it. Having unscrewed it, it is necessary to remove the jibeler itself from its body.
  • From the opposite side, unscrew and remove the gasket housing in the same way, then the jecler itself is removed from the housing.
  • Unscrew the four acceleration pump diaphragm fastening screws. Now remove the cover, spring and diaphragm.
  • Then remove the stretch spring lever of the pneumatic drive, pull the lock-latch of the thrust and remove it from engaging with the throttle lever. We unscrew the fastening screws and remove the pneumatic drive from the carburetor.
  • At the last stage, the cutter is a carburetor by dismantling the throttle housing. Unscrew the two housing fastening screws and remove it together with the sealing gasket. Remove the economizer and microswitch of the EPHX block. Then we turn the inspection screws of the idling and the quality of the mixture.
  • The hull of the carburetor is placed in the container where the acetone is preliminarily poured, and let it be squeezed out from Nagara. Check the condition of all components and, if necessary, change the defective elements to new ones. Do not clean the jets with metal wire, because there is a risk of damage to the inner surface of the channels. Discover the jets in acetone, and then blow with compressed air.

How to remove the accelerator pump

To remove the accelerator pump from the carburetor, unscrew the four fastening screws of its covers, and then another screw fixing directly the accelerating pump itself. Then pull it out of the housing.
