3.4 Starting the engine for the first time
1. Prime your system for the first time (or non-use for long time) by removing the fuel line
from the inlet of the throttle body
2. Cycle the battery power to the ECU in 5 second intervals until fuel is flowing from the
fuel line. Re-install the fuel line. You should not have to complete the priming process
again unless the engine fuel system is allowed to run dry or has been disconnected for any
reason
3. Manually hand rotate the propeller in few circles to make sure the hall sensor is working
in normal status (the sound “da.da”) with green LED light on & flashing in sync when the
engine is running in high speed, now next step starts after the fuel is in
。
4. Verify that the throttle setting is at about 30%
5. The engine should be started using an external spinner, or using a built-in starting
alternator ( Be available on our One-Key Starter version soon).
Flip starting as an
additional option but is not recommended due to possible injuries
.
Note:
The engine may struggle to run for the first few minutes as it is purging all the air
from the fuel system.
This may not be evident until you go to wide open throttle
6. Allow the engine to run for a few minutes to warm up the engine
7. Hold at wide open throttle for 15 seconds to verify that the air in the fuel system has been
purged. Reduce the engine speed to idle
