Primer
Another way to enrichen the fuel air mixture for start-
up is the primer. The primer is a simple pump that pressur-
izes the float chamber, forcing fuel out the main nozzle.
See Figure 4.15.
Carburetors that use a primer are easily identified by
the lack of a choke plate and the addition of a primer port.
See Figure 4.16.
To remove/replace the primer:
1. Remove the air filter housing by following the steps
described in Chapter 3: Air Intake And Filter.
2. Disconnect the primer line from the primer bulb. See
Figure 4.17.
