Disassembly and reassembly

CAUTION:
Separation of the carburetors is not recommended. Usual disassembly for cleaning and inspection does not require separation of the carburetors. The carburetor body support screws are locked with a locking compound such "LOCTITE". If the carburetors are separated, misalignment will result.

1. Loosen the starter lever securing screws and remove the starter lever shaft.

2. Remove the vacuum chamber cover and remove the spring and diaphragm (vacuum piston).

NOTE:
Note that there is the tab on the rubber diaphragm. There is the matching recess in the carburetor body for the diaphragm tab.

3. Remove the pilot air jet.

4. Remove the screws holding the float chamber cover and remove the cover. The main and pilot jets are located in the float bowl. Remove the jets if necessary.

5. Pull out the float pivot pin. Remove the float assembly. Be careful to not lose the float valve under the float arm. Remove the float valve seat.

6.    Reasemble in reverse order. Pay close attention to the installation of the vacuum piston diaphragm and the location of each jet.

7.    If the carburetors should be separated, care must be taken so that they are put together in place according to the following procedures:

a. Place the carburetors on a surface plate and install the lower support plate. Apply a thread locking compound such as "LOCTITE" and tighten the screws securely while holding the carburetor body.

NOTE:
When reassembling, the surface plate should be used for the proper carburetor alignment.

b. Install the upper support plate. Apply a thread locking compound such as "LOCTITE" to the support screw threads and tighten the screws securely.
