B. Mount 12 & 16 hp Engine with 3/8-16 x 1 Cap Screws and Lock Washers coming up from
underside of #1E Mount and engaging the 3/8-16 threads in bottom of engine. In both case;
above square Engine in Body (Crankshaft should be at approximately a 90° angle with the
inside of the left #1AL Body Wall) and then tighten the four Cap Screws. At this point,
loop the #33 Drive Belt around the #32 Pulley.
27. Slide #2 Grill into front of Body and align the four 3/8" holes. Insert 3/8-16 x
1-1/4 Cap Screw into 3/8 WI Washer and then from outside body, insert cap screw into each
of the four 3/8" holes. On the inside, secure with 3/8 WI Washer and 3/8-16 Locknut.
NOTE: If you have the light kit, install the #18 Light Brackets on the outside of Body
Walls using the above assembly. (Check Drawing).
28. Insert #42 Throttle Control into the 9/16" hole on the left of #1C Brace. Secure
below with Lock Washer and Nut provided. Using the "Throttle Control Wire" Drawing for
your particular Engine Horsepower, slide the wire "casing" into its respective Bowden
Wire Clamp at the Throttle on Engine. Engage the offset end of Bowden's "inner Wire"
into the 1/16" hole in your particular Engine Throttle lever. With #42 Throttle Control
Handle pushed all the way in, the Throttle Lever should be pushed to the slow (idle po-
sition) so that the throttle on the carburetor is closed and resting against the idle
adjustment screw. Now, tighten the Bowden Wire Clamp.
29. On 7 hp Engine (only): Attach the 3/16 ID loop ends of #6Z and 6Y Wires to #51
(on-off) Switch. (Note wire positions in Drawing) from inside Tractor Body, insert
Switch into left front 1/2" hole followed by "on-off" switch plate. Turn Switch so
"on" is forward and secure with nut provided. Check Step #28: Pulling up on Handle
of #42 Control should open the Throttle Lever to the "fast" position. (NOTE; To hold
a particular Throttle setting, give the control a 1/4 turn to lock in place).
30. Insert the shorter #43 Choke Control into the remaining 9/16" hole on right of #1C
Brace. Secure below with Nut and Lock Washer. Run Control "casing" rearward and loop
around inside #1M Baffle and insert into Bowden Wire Clamp mounted to clip bolted to
Engine's housing. Engage "offset end" of Bowden's Inner Wire into hole on Engine Choke
Lever above carburetor. (NOTE: Do not use hole in middle of "arrow" on Choke Lever.)
With #43 Choke Control pushed in, the Choke Lever should rotate toward the Air Cleaner
and stop. At this point, tighten the Bowden Wire Clamp. Check Choke Control, pulling
out #43 Control Handle should rotate Choke Lever so that it stops at a point perpendi-
cular to the engine Crankshaft.
31. On 7 hp Engine only; Pull up on Engine Starter Rope and tie a "loop knot" to keep
it from retracting. Remove Handle from rope and inset rope through 3/8" grommet above
recoil starter. Reassemble Handle on rope end and remove knot to allow rope to recoil.
Insert "plug" end of #6Y Wire onto "spade" terminal mounted to Engine frame located
beneath gas tank.
