Choke
MTD engines are equipped with a choke, a primer or
both. If equipped with a manual choke, it must be closed to
start the engine. The choke should be opened when the
engine starts. This can be a source of starting issues with
customers who are not familiar with manual chokes.
The choke is operated by either a knob or a lever at the
carburetor, depending on the application. If the choke plate
fails to close fully, the engine will be difficult or impossible
to start when cold. See Figure 4.12.
NOTE: Engines with a choke lever do not have any choke
linkages. The choke lever is mounted on the car-
buretor and directly connected the choke plate.
See Figure 4.13.
