Manual Choke
If the engine is equipped with a manual choke, the choke must be closed to start the engine and opened when
the engine starts. This can be a source of starting issues with customers who are not familiar with manual chokes.
The manual choke is operated by a pull knob at the carburetor or on the handle bar, depending on the applica-
tion. If the choke plate fails to close fully when the knob is pulled, the mower will be difficult or impossible to start
when cold.
NOTE: The rod connecting the choke lever to the
choke arm on the carburetor can be bent
slightly to facilitate adjustment. See Figure
4.29.
Autochoke
The MTD engine uses a simple autochoke system that
is similar to the old style air vane governors. When the
engine is at rest a spring holds the choke in the closed
position. See Figure 4.30.
