Lightweight.
Excellent power-to-weight ratio.
Ability to operate in any position.
Easy maintenance.
Simple construction.
The Toro 2-cycle engine used on Toro Gas Power
Shovels is a third-port, loop-scavenged design. This
design name describes the path of the fuel/air mixture
into the crankcase and combustion chamber, and the
exhausting of spent gases (Figure 196). The piston in
Figure 196 is shown in a lower than normal position, to
clearly show the individual ports.

Now, turn the ignition switch to the “ON” or the 2
o’clock position. Visually check to ensure that the
switch actuator is not in contact with the contact
switch terminals. The tester should not register
continuity when the switch is in the “ON” position
(Figure 195). Switch parts which are loose, bent,
or damaged should be replaced.

Single Stage Snowthrower Service Manual
9 - 7
(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.
