Predator Engines 212cc Owner's Manual & Safety Instructions page 7

High Altitude Operation Above 3000 feet
At high altitudes, the engine's carburetor, governor (if so equipped), and any other parts that control
the fuel-air ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude
use and to prevent damage to the engine and any other devices used with this product.
The fuel system on this engine may be influenced by operation at higher altitudes.
Proper operation can be ensured by installing an altitude kit at altitudes higher than 3000 ft. above sea level.
At elevations above 8000 ft, the engine may experience decreased performance, even with the proper main jet.
Operating this engine without the proper altitude kit installed may increase the engine's emissions and
decrease fuel economy and performance. The kit should be installed by a qualified mechanic.
WARNING! TO PREVENT SERIOUS INJURY FROM FIRE:
Follow kit procedures in a well-ventilated area away from ignition sources.
If the engine is hot from use, shut the engine off and wait for it to cool before proceeding. Do not smoke.
NOTICE Warranty void if necessary adjustments are not made for high altitude use.
High Altitude Kit Installation Instructions
1. Turn off the engine.
2. Close the fuel valve.
3. Place a bowl under the fuel cup to catch any spilled fuel.
4. Unthread the bolt holding the fuel cup.
CAUTION! Carburetor bowl may have gas in it
which will leak upon removing the bolt.
5. Remove the bolt, bolt seal, fuel cup, fuel cup seal and main jet
from the body of the carburetor assembly. A carburetor screwdriver
(not included) is needed to remove and install the Main Jet.
Note: The mixing tube is held in place by the main jet and
might fall out when it is removed. If it falls out, replace it in
the same orientation before replacing the main jet.
6. Replace the main jet with the replacement jet
needed for your altitude range (part 1 or 2).
Note: The Fuel cup seal and bolt seal may be damaged during
removal and should be replaced with the new ones from the kit.
7. Replace the Fuel Cup Seal
(4), fuel cup, Bolt Seal (3) and bolt. Tighten in place.
CAUTION: Do not cross thread Bolt when tightening. Finger tighten first and
then use a wrench to make sure the Bolt is properly threaded.
8. Wipe up any spilled fuel and allow excess to evaporate before starting engine.
To prevent FIRE, do not start the engine while the smell of fuel hangs in the air.
