*Air cooling:
Large capacity, curved vane blower casting, integrated
with flywheel. Air passes through deep fins to maintain
optimum operating temperature of engine.
*Ignition:
Magneto with waterproof molded ignition coil and
dust-proof breaker point enclosure.
Breaker system standard. (Electronic ignition system
available as optional specification.)
*Lubrication:
Splash type.
*Carburetor:
Pulse pump type, with idle mixture adjustment.
*Air cleaner:
Semi-dry type, washable polyurethane element with
nylon brush.
*Fuel tank:
Sheet metal.
*Governor:
Mechanical fly-weight ty,pe, running in crankcase oil.
"Governor control:
Adjustable speed control. Remote speed control joint
optional.
*Cylinder and crankcase:
One piece hypereutectic aluminum-silicon alloy die-
casting with plateau-honing.
"Piston:
Hard-chrome plated aluminum alloy.
*Piston rings:
Two compression rings including silicon carbide (on an
iron base) plated top ring. One oil control ring.
*Connecting rod:
I-beam cross section, heat
treated aluminum alloy,
with large bearings.
*Crankshaft:
Heat treated ductile iron integrated with counter
balance weights and camshaft drive gear. Induction
hardened
crankpin and main journals.
*Main bearings:
P.T.O. side, ball bearing. Magneto side, lead bronze
sintered alloy plain bearing with steel back metal.
*Valves:
Forged 21 -4N austenitic sizinless steel exhaust valve.
Forged heat-resisting steel intake valve.
*Valve seats:
Exhaust; Sintered alloy insert (Co-W-Ni-Cr-Mo) on an
iron base.
Intake;
Sintered alloy insert (Cu-Mo) on an iron
base.
"Valve guides:
Exhaust; Sintered alloy insert (Cu-P-Sn) on an iron
base.
Intake;
Directly borne by cylinder/crankcase. Die-
casted hypereutectic aluminum-silicon alloy,
machined.
*Valve tappets:
Wear resisting stamp-forged steel, hardened and
ground.
*Breather:
Vacuum type, vented through air cleaner to prevent oil
spill.
"Muffler:
Sheet metal painted with heat-resisting paint, effec-
tive noise suppression. (Optional parts available.)
"Starter:
Recoil starter with safety cover as standard. (Optional
parts available)
*Direction of rotation:
Counterclockwise, viewed from power take-off side.
"Finish:
Anti-rust, painted.
