are staggered and the cylinder is in the correct position.
Use fingers to compress the piston rings and push
the cylinder onto the piston. Do not rotate or twist the
cylinder (diag. 7-16).
11. Install Torx bolts and alternately torque the bolts to
80-95 inch pounds (9.04 Nm - 10.7 Nm), or on engines
with studs instead of bolts: push the cylinder down to
a depth where the nuts can be started on the studs.
Finger tighten the nuts, use a wrench to snug, and
torque the nuts to 70 -100 inch pounds (7.9 Nm - 11.3
Nm) using a crowfoot on the torque wrench.
12. Install the exhaust gasket, muffler, spark arrestor if
applicable, bolts or muffler springs. Torque the muffler
bolts to 85 - 105 in. lbs (9.6 Nm - 11.8 Nm) of torque if
applicable. The longer ends of the springs hook into
the bosses on the cylinder. Use heavy gauge wire (as
shown in the tool section) to stretch and hook the
muffler springs (diag. 7-17). Install the muffler heat
shield if applicable. Remove the engine holder.
13. Attach the blower housing base using the three screws
removed from the engine holder and torque the screws
to 30-40 inch pounds (3.3 Nm - 4.5 Nm).
14. On TC type I models, install the governor air vane
assembly into the blower housing base as shown.
Some models use a spring clip to hold the air vane in
position. Insert and tighten the speed adjusting lever
holddown screw to the blower housing base. Hook the
long end of the governor spring into the notch on the
neck of the air vane. The short end hooks into the hole
in the speed adjusting lever as shown (diag. 7-18).
15. Insert one end of the throttle link in the hole in the air
vane and the other end in the hole closest to the throttle
shaft. Install the air baffle if equipped, gaskets, spacer,
and carburetor. Assemble gaskets correctly, do not plug
the pulse passage. Torque the bolts to 30-40 in.lbs.
(3.3 Nm - 4.5 Nm). On TC type II models, attach and
torque the air vane to the carburetor throttle shaft
before installation. Hook the long end of the governor
spring in the hole in the air vane and the short end in
the hole in the speed control bracket. The spring hooks
from beneath both components. Use the illustration
(diag. 7-19) and the following spring location chart if
the air vane has more than one governor spring hole
and uses a colored spring with a square and round
end.

Orange or Green
Pink, Red, OR Black
16. Install the flywheel key and flywheel. Install the flywheel
washer and nut, use a strapwrench (part# 670305) to
hold the flywheel, and torque the nut to 15-20 foot
pounds (1.6 Nm - 2.2 Nm).
