CHAPTER 5 REWIND STARTERS
GENERAL INFORMATION
TC/TM series engines have the recoil assembly as a part of the engine's blower housing. Two different styles of recoil
starters are used along with different starter rope locations. Use the engine model and specification number to identify
the recoil style and correct replacement parts.
OPERATION
TC TYPE I
As the starter rope is pulled, the starter pulley rotates on
the center leg of the starter. The starter pawl is connected
to the starter pulley by an offset hole in the pawl and a
corresponding raised boss on the pulley. The pawl has an
oversized inside diameter which allows the pawl to be
pulled off center. The flat contact surface of the pawl
engages with one of the flywheel fins. This engagement
turns the flywheel until the engine fires and the flywheel
speed exceeds the speed of the starter pulley. The
flywheel fins push the pawl (using the ramp side) to the
disengaged position. The brake spring slows the pulley
and pawl from turning (diag. 5-1).
TC TYPE II/TM
This starter uses two engagement pawls bolted to the
flywheel with shoulder bolts. Each pawl uses an
engagement spring to keep the pawl in contact with the
pulley hub. The pawls lock into two of the four notched
surfaces located on the starter pulley when the starter
rope is pulled. When the engine fires and the flywheel
speed exceeds the speed of the starter pulley, the pawls
disengage, and centrifugal force keeps the pawls in the
disengaged position (diag. 5-1).
COMPONENTS
1. Blower Housing
2. Recoil Spring
3. Washer
4. Pulley
5. Pawl
6. Brake Spring
7. Retainer
SERVICE
Starter related problems will require the starter to be
removed from the engine to diagnose the cause. On TC
Type I engines, try starter operation off the engine to see
pawl engagement. Visually inspect the starter pawl, brake
spring, retainer, pulley, washer(s) and rope for wear or
breakage. Repair or replace as necessary. On TC Type II/
TM engines, recoil disassembly is necessary only if the
pulley is worn, the recoil will not retract, or the rope needs
replacement. Check starter pawl engagement on the
flywheel for broken springs, sticking or bent condition, or
loose pawl screws.
DISASSEMBLY PROCEDURE
1. Remove the fuel tank spring and recoil assembly
from the engine. On TC Type II/TM engines, the air
filter and fuel tank must be removed before the
recoil assembly.
