4. The plastic baffle installed in the fuel bowl should be removed and reinstalled when the carburetor
is assembled. This baffle is essential to proper float operation and should not be left out. Dual feed
bowls utilize the inlet cavity as a baffle, so a separate piece is not required.
5. Removal of four Phillips screws allows the accelerator pump housing to be lifted from the fuel bowl
(Fig. 3). The pump diaphragm is located below this cover. This should now be discarded as a new
diaphragm is included with your package. A return spring is located beneath the diaphragm and it
should be saved for reuse.

6. The metering block must also be stripped of its removable parts prior to being cleaned. The jets
should be removed with a wide-blade screwdriver. Make a note at this time, of the jet number, so
that during reassembly, the jets will be reinstalled in the proper metering block.
7. The power valve can be removed from the metering block with a 1-inch socket, open-end or box
wrench (Fig. 4). However, when using either of the latter tools, care must be taken to avoid
damaging the sealing beads on the block surface.
