CHECK THE FOLLOWING:
A. BE SURE EQUIPMENT IS IN NEUTRAL GEAR WITH
CLUTCHES, BELTS, CHAINS AND SAFETY SWITCHES
DISENGAGED. (FOLLOW EQUIPMENT MANUFACTUR-

SAFETY SWITCHES IN SAFE STARTING POSITION.
B. Be sure spark plug wire is attached to spark plug (see
Figure 2).
C. Be sure any ignition switch on engine or equipment is in
“ON”, “RUN” or “START” position.
ENGINES WHICH ARE CERTIFIED TO COMPLY WITH CALIFOR-

GINES:
Are certified to operate on regular unleaded gasoline / oil mix. Include
the following emission control system(s): EM, TWC (if so equipped);
Do not include any user adjustable features - therefore no other
adjustments are need.
OIL & FUEL RECOMMENDATIONS
А А
USE CLEAN, HIGH QUALITY 2 CYCLE OIL,
NMMA TC-WII, OR TC-W3.
TECUMSEH SPECIALLY FORMULATED OIL IS
RECOMMENDED AND AVAILABLE FROM ANY AUTHORIZED
TECUMSEH SERVICE OUTLET BY SPECIFYING PART
NUMBER 730227.
DO NOT USE MULTI-VISCOSITY OIL!
Á
A FRESH, CLEAN, UNLEADED REGULAR,
UNLEADED PREMIUM, OR REFORMULATED
AUTOMOTIVE GASOLINE ONLY. DO NOT
USE LEADED GASOLINE.
NOTE: Do not use gasoline containing methanol (wood alco-
hol) fuel containing up to 10% ethanol (gasohol) or up
to 15% MTBE (Methyl Tertiary Butyl Ether) may be used
but requires special care when the engine is not used
for extended periods. See "Storage" instructions.
Â
MIXING OIL & GASOLINE
THE FUEL/OIL MIX RATIO IS 50:1 WITH THE USE OF A NMMA
CLASSIFIED OIL.
FOR NEW ENGINES:
USE TWICE THE NORMAL OIL
QUANTITY FOR THE FIRST GALLON OF FUEL.
NOTE: 32:1 fuel/oil mix ratio is recommended with non
NMMA oils. (Due to differences in fuel and oil avail-
ability worldwide, Tecumseh recommends a 32:1 mix
ratio if NMMA oil is not available.)
