THREE BASIC CARBURETOR STYLES
There are three styles of carburetors used on Briggs &
Stratton engines. Page 3 and i, Fig. 8. Compare the
carburetor to be repaired with the illustrations to
determine style of carburetor and refer to that section for
repair information.
Before removing any carburetor for repair, look for signs
of air leakage, or mounting gaskets that are loose, have
deteriorated, or are otherwise damaged.
Note position of governor springs, governor link, remote
control or other attachments to facilitate re-assembly.
Do not bend the links or stretch the spring. (Section 4
illustrates popular engine models.)
