CONTROLS/LOCATION AND OPERATION
PRIMER
The primer, used on most single stage snowthrowers,
is designed to pump a small amount of fuel from the
carburetor into the carburetor throat. This extra fuel
mixture allows the engine to be started in cold
temperatures.
The primer is operated by depressing the primer bulb
with a finger, ensuring the finger covers the vent hole in
the bulb. Depress the primer button, release, wait
about 3 seconds, then depress the primer again.
Repeat as often as needed. The pause in between
primes allows time for the prime well in the carburetor
to refill.
Operator priming instructions vary depending on the
year your snowthrower was manufactured. On those
units manufactured from 1972 and before, in a cold
start application, the primer should be pressed
approximately 10 times (Figure 11). The 1973 through
1977 single stage snowthrower primer should be
pressed 5 times. Snowthrowers produced from 1978
through 1980, the primer should be pushed one to four
times (Figure 8, Figure 11, or Figure 12). For
temperatures above +20° F (-7° C) use one or two
primes; below +20° F (-7° C) use three or four primes.
For extremely cold temperatures below -10° F (-23° C)
use five or six primes. For 1981 and newer models,
depress the primer one or two times, with a pause in
between. Additional primes may be necessary in
colder temperatures.

Note: On early production, the diaphragm cover was
vented, and on later production, the primer bulb
incorporates the vent. Those models with a vented
diaphragm cover require more primes.

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.
