CHAPTER 5 RECOIL STARTERS

GENERAL INFORMATION

Recoil starters used on vertical shaft Tecumseh engines are top mount horizontal pull style. Horizontal shaft

engines use recoil starters which can be mounted to pull either vertically or horizontally. All recoil starters turn

the engine over by engaging a dog(s) into the starter cup attached to the engine flywheel. All starters are

spring loaded to retract the dog(s) when the engine speed exceeds the turning speed of the starter.

OPERATION

As the starter rope is pulled, the starter pulley rotates on the center pin. The starter dog(s) is pinned or

pocketed in the pulley hub and extend outward when the pulley rotation forces the starter dog(s) to contact the

ears on the retainer. The retainer ears act as a ramp to fully extend the starter dog(s). The fully extended

starter dog(s) locks in contact with notches in the starter cup. When the engine fires and the rotational speed

of the starter cup exceeds the starter pulley, the starter dog(s) disengages from the starter cup. The starter dog

spring(s) returns the starter dog(s) to the disengaged position. When the starter handle is released, the recoil

spring turns the starter pulley in the opposite direction to retract the starter rope.

COMPONENTS

SERVICE

Starter related problems will require the starter to be removed from the engine to diagnose the cause. Visually

inspect the starter dog(s), starter cup, retainer, springs, rope, washers, and the starter pulley for wear or

breakage. Use one of the following procedures that apply to the application to disassemble, repair, and assemble

the starter. Always consult the Tecumseh Master Parts Manual for the correct replacement parts.

ROPE SERVICE

Rope replacement should be done using the correct part number replacement rope or braided rope of the

correct diameter and length. Consult the Tecumseh Master Parts Manual to obtain the correct part number,

length, and size required. Use the following rope chart to convert a numbered rope to a fractional diameter for

bulk rope use. The rope ends should be cauterized by burning with a match and wiping the rope end with a

cloth while hot.
