Most paramotors share a common design.  If you cannot find the info you need below, check the specific sections of your particular engine.

Bearing condition

Bearing replacement

Belt adjustment – How to adjust the redrive belt on any engine

Breaking in a new engine – a new engine generates more friction than usual.  It MUST be broken in carefully so it will last.

Carburetor Dimensions – by Gerry Farell – This information compares the dimensions of the various Walbro carburetors and is helpful if you are considering upgrading from the WG-8 to another Walbro model.

Compression check – One of the best ways to quickly check the overall health of an engine.

Crankcase pressure test – The only way to be sure the main seals and various gaskets are not leaking.

Cruise control – Not a good idea and here is why (page down to the end).

Cylinder head temperature gauge – Not having a CHT is like driving a car without any gauges or warning lights. Most of the time you don't need them....

Fuel & 2 Stroke oil specifications – Pilots must use the correct gasoline and oil for long engine life

Fuel filter – Unfortunately, the fuel filters that auto stores stock are not very good quality.  Here is some helpful advice.

Spark plug info – Meaning of the NGK part number

Spark plug installation

Speed system pulleys – pilots are plagued with the poor quality, high friction Viadana pulleys from Miniplane.  Here is an alternative: the Harken

Starting a paramotor – with this technique, your engine will start with the first pull every time.

Tachometer – Is your engine due for routine maintenance?  Has power output changed?  You won't know without a tachometer/hour meter.

Threadlock – An important item in a pilot's toolbox

Throttle cable – Cleaning, modifications, and cruise control info.  For kill switch issues, see "kill switch problems" above.

Throttle placement in the hand while launching a paramotor.
