Kick starter
1. Check the ratchet teeth on the kick gear
and
ratchet wheel. The mating edges
should fit flush against each other. If
there is severe rounding off, replace as
set.
2. Check
to see that the kick gear spins
freely on the kick axle. If not, replace
either or both as required. Replace if
any signs of galling are found.
3. Check
to see that the ratchet wheel
(splined) slides freely on the kick axle.
Check
for burrs or other damage.
Replace as required.
4. Check axle and
wheel splines for wear.
The
ratchet wheel is a fairly loose fit on
splines.
However, if wheel is so loose it
catches on shaft keeping ratchet wheel
spring from forcing it out, replace.
5. Check
the ratchet wheel and kick gear
for damage, replace as required.
6. Check
the kick pinion gear, second pi-
nion gear and spring for damage,
scratches, wear and fatigue.
