event. This is when you could hurt your engine because it will be running to lean to fly at the lower
elevation and you could over heat and burn out your engine.
Flying in the Mountains
When you begin your flight let’s say starting elevation is 5000ft. You will need to run the engine a little
leaner as the amount of oxygen in the air is less, and so you will not burn as much fuel. There is less
concern about killing your engine when moving from the beach to the mountains to fly as you will be
running the engine to rich, and this could cause the engine to miss-fire or run rough during your flight.
Air Temperature and Density
The Air temperature you fly in can also affect the density of the air and how the air fuel mixture works
in your engine. Warm humid air is less dense then cold dry air and if you were flying in these conditions
you should check your spark plug to make sure you are not running to rich. If you are flying in a cold dry
location the air is more dense then warm humid air, and you run the risk of running lean and
overheating your engine. Being aware of these environmental conditions at any elevation will help
assure your engine is always running correctly.
Inlet Carb Filter could be clogged:
Another reason that your engine could begin to overheat is due to the Inlet Carb Filter where the fuel
comes into the carburetor becomes clogged. This is just a little screen inside the carburetor that keeps
particles from entering your engine through the fuel. As you run your Paramotor this will filter out
particles and begin to restrict the fuel that can enter the carburetor. As a part of the maintenance you
perform on your Paramotor you want to periodically check on, and clean this filter to assure your
carburetor is working correctly. This will make sure the fuel can easily enter the carburetor which
impacts the Fuel to Air mixture. Please read the carburetor section of this manual to learn how to clean
the inlet carb filter.
Vacuum Leak around the engine:
While a vacuum leak is less common, it can occur if you neglect the maintenance on your engine. The
most common bolts to check would be the Cylinder Head bolts to make sure these are tightened to the
correct torque specification. A visual cue that you may have a vacuum leak is you will see an oil leak
from where parts come together. This can occur around the engine crankcase parts all the way up to
the cylinder head. A vacuum leak will force your engine to run lean causing it to run hotter than
normal, and in extreme cases you will notice a loss of power.
The other areas to check are parts on your engine that use a gasket to create the seal between the part
listed below and the engine. These include:
Cylinder Base
Cylinder Head Gasket
Carb Mounting Gasket
Reed Valve Gaskets
Crankcase Seals
If you feel you still have a vacuum leak after inspecting the areas listed above, then you may have
another issue, and you should contact the engine manufacturer. As you fly your Paramotor you will
