2) Starting the Engine:
Check your surroundings and verify the area is clear. Securely grasp the paramotor frame near where
the engine mounts to the frame in your free hand. Check to see that the throttle is in the idle only
position and then start the engine using a smooth full stroke when pulling. If it does not start on the first
or second pull stop, prime 1 second and try restarting the engine.
3) Engine Starts / Warm-up and Fine Tuning.
Warm the engine to its normal operating temperature before flying and fine tune if required (See
Tuning
Your Carburetor
).
BLACK DEVIL ENGINE TROUBLESHOOTING:
Most starting and operating issues can easily be traced down to either a problem with fuel system, or with
the electrical system. When diagnosing problems begin with the most simple and move to more complex
issues such as: Is the correct amount of fuel reaching the carburetor? Is there enough spark to cause
the engine to turn over? Below is a brief list of items to check based on easiest and most common, to
the more difficult,
THE ENGINE DOES NOT START
Switch is on, Master switch is on (if applicable)
Fuel reaches the carburetor / engine primed properly
Battery is fully charged (if applicable)
Good spark plug / connection
Idle speed set too low (2400 RPMs recommended)
Belt is tight
Auto Decompressor clean and closed
Carburetor is clean / adjusted properly
Carburetor pop off pressure is incorrectly set
Additional information concerning these systems is discussed below or is found, or throughout this
manual under the appropriate topic. Not all areas are discussed in full and may require some mechanical
background to check and diagnose.
Electrical
Switch on-off
Cable of the spark plug is connected and secure
Kill switch wire is in good condition and improperly grounded with the frame
Spark plug is in good condition, clean, and gapped properly. Remove and inspect / replace
Battery is fully changed, and all electrical connections are secured
Insufficient spark. Remove spark plug from the cylinder. Plug the spark plug wire back on to the
spark plug. While holding the plug by the wire, place the electrode near the metal part of the
frame @ 1/8 -
1/4” away and have an assistance try starting the motor. Note the strength of the
spark across the gap between the electrode and the frame. You should have a blue spark.
Coil wire is loose / faulty or grounded Check the coil grounding wire from the coil to make sure it
is not touching metal.
Coil gap is improperly set (set to 0,35-0,4 mm)
