We don't suggest using more oil than recommended since damage to the piston rings and piston could result.
We also don't suggest adding performance-boosting additives to your fuel. Doing so will void your engine's
warranty.
IMPORTANT
Always mix your fuel in a clean container and filter it before filling your fuel tank.
Spark Plug Recommendation - MUST be a “RESISTOR” type Recc. type is – NGK BMR6a
The spark plug included with your engine is designed specifically for your engine.
When purchasing a new spark plug we suggest double-checking the gap using a gap gauge tool found at auto-
parts stores. The spark plug gap should be set to a gap of .025 - .03 with the spark plug cold. The spark plug
should be replaced when signs of electrode wear are present.
High Speed Needle Valve
The high speed needle valve is used to meter the air/fuel mixture at full throttle. Turn the needle clockwise to
lean the mixture or turn the needle counterclockwise to richen the mixture. The high speed needle valve is preset
from the factory for initial starting. It will need final adjusting to suit your atmospheric conditions, fuel,
temperature, altitude, etc.
Low Speed Needle Valve
The low speed needle valve regulates the air/fuel mixture at idle and during transition from idle to full throttle.
Turn the needle clockwise to lean the mixture or turn the needle counterclockwise to richen the mixture. The low
speed needle valve is preset from the factory for initial starting. It will need final adjusting to suit your
atmospheric conditions, fuel, temperature, altitude, etc.
Idle Adjustment Screw
Although we suggest using your transmitter's idle trim lever to set the idle speed of the engine, you can also set
the idle speed of the engine using the idle adjustment screw on the carburetor. Turning the screw clockwise will
increase the idle speed and turning the screw counterclockwise will decrease the idle speed. The screw is set at
the factory and should not require adjustment.
If your high and low speed needle valves get too far out of adjustment, use this information to reset them to the
factory settings.
High Speed Needle Valve:
Turn in until it stops and back out 1-1/2 turns.
Low Speed Needle Valve:
Turn in until it stops and back out 1 turn.
The starting procedure for the 46cc gasoline engine is actually quite simple. For ease of starting we recommend
using a high-torque electric starter with a quality 1 2V motorcycle battery or a car battery. The engine can be
started by hand, but only using a chicken stick. We strongly discourage it, but if you must use your hand to start
the engine, you MUST wear a heavy-duty leather glove.
Verify that the ignition kill switch is in the "off" position and fill the fuel tank with fresh, filtered fuel.
Before filling the fuel tank, gently shake your fuel container to remix the oil and gas mixture.
Set the throttle to the idle setting. The throttle must be at the idle setting so that the timing is in the correct
position for engine start-up.
Pull the propeller counterclockwise through the compression stroke 4 - 6 times to prime the engine, leaving the
propeller just below the top of the compression stroke the last time you pull it through.
