Drain all fuel from the gas tank. Refer to "Draining
The Fuel Tank" on page 9 - 4.
2.
Start the engine and let it warm up for
approximately five minutes. Do not adjust the
carburetor when the engine is cold. Be sure to
perform carburetor adjustments while at a
temperature that will be the average outdoor
temperatures at which the Power Shovel will be
used.
Remove upper shroud. See "Removing The
Upper Shroud" on page 9 - 4.
Place the gas cap on the gas tank to contain gas
fumes and excess fuel/oil mixture from dripping
out of the tank during service.
CAUTION

6.
Remove both the fuel line and primer hose from
the carburetor.
The engine must be running so final adjustment
of the carburetor can be performed. To guard
against possible personal injury, keep hands,
feet, and face away from concealed, moving, or
rotating parts.
Loosen the carburetor hex socket head screws
with an 1/8 inch allen wrench.
As the carburetor is being removed, disconnect
the choke linkage from the choke lever (Figure
203).
NOTE: When making the adjustment, turn the
adjustment screw 1/8 turn at a time and wait for
the engine to respond to change.
3.
With the engine running, turn the mixture
adjustment screw slowly clockwise until engine
falters. Remember this location. Now turn the
screw counterclockwise until the engine just starts
to sputter. Remember this location. Turn the
screw clockwise until it is halfway between the first
position where your engine faltered and the last
position where your engine started to sputter.
This should be the optimum setting on your
carburetor.

NOTE: In extremely low temperatures or heavy
loading conditions, the mixture adjustment screw
may have to be rotated counterclockwise another
1/8 turn.

Single Stage Snowthrower Service Manual
(3 votes, average: 4.67 out of 5)
Lawn and Garden readers have rated Toro Single Stage Snow Blower Service Manual 4.7 out of 5.0 based on 3 product reviews. EXCELLENT . Hard to find manual and very detailed . Only downside is the pics and wording in pics are backwards , but I can deal with that
The manual provides detailed step-by-step instructions for engine removal and installation but there is nothing in it about repair of the recoil starter. The engine removal instructions will be helpful because the starter is buried behind the fuel tank and engine support bracket. I think my problem is a sticking starter dog but getting to it will be a major project.
