d) So what do I need to start this model?
The Zenoah motors are supplied with a pull starter. This can be permanently mounted or
made removable. This is one way to start the motor.
In addition, you can use a standard spin starter on the start shaft above the clutch. The
G231/G26 motors can be started in this method using a typical starter for .90 size glow
motors and the Pro-Flex starter wand. This works so well, it is the recommended method.
e) So how do I go about starting the model?
Develop a routine and follow it every time:
Depress the primer bulb on the carburetor until there are no bubbles or air in the fuel
line. This will take a few pumps.
Make sure the throttle is set at the starting position, about 10% open from full closed.
You may need to adjust the throttle trim as necessary.
If you’re using a pull starter, the engine will need to be choked (by closing the choke
lever) and pulled through 4-5 times. Then open the choke and the motor should start
with 1-2 pulls.
If you’re using the recommended spin starter, you won’t need the choke.
Always hold on to the rotor head with one hand when starting the motor to prevent it
from accidentally hitting you.
Any time that the motor has been sitting for a few hours, it will idle at a much higher
RPM than the trim is set for. As the motor warms up, it will slow down and settle in to an
idle. The clutch has been designed to allow for this. It is a normal part of the startup
routine.
If the motor does not start and you have set the mixture to the initial settings try
increasing the idle trim slightly, however do not increase too much or the model may
start and get away from you.
