Use new gaskets and seals. Make sure that new gaskets fit correctly and that all holes and slots are punched through and correctly located. To reassemble carburetor, reverse disassembly procedure and note the following:

1. Apply petroleum jelly to all "O" rings before installation.
2. Make sure projection on the choke rod is positioned under the fast idle cam. This will ensure that fast idle cam will be raised up when the choke valve closes.
3. It will be necessary to install the secondary diaphragm housing cover and all 4 screws before diaphragm housing is installed onto main body.
