Maintenance
After each flying session:
1. Fully drain the fuel from the tank.
2. Start the engine and run it until the fuel is
completely run out of the engine.
3. Try starting the engine three more times or until
it will no longer fire. This gets all the fuel out of
the engine.
Now add several drops (about 10) of after-run oil
(EVOX1001 Evolution Engine's Blue Block Rust Inhibitor)
should be applied into the carburetor and the engine
should be turned over for a few seconds with the starter.
This will prevent rust and corrosion.
If you need additional help or have any questions, please call
the appropriate Horizon Product Support department. Horizon
has trained technicians who are qualified to answer your
engine questions.
