Most paramotors share a common design. If you cannot find the info you need below, check the specific sections of your particular engine.
Assembly of a paramotor – here are the basics
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....
De-carbonizing a two stroke engine – Alex Varv shows how to do it without removing the cylinder
Fuel & oil specifications – Pilots must use the correct gasoline and oil for long engine life
Fuel system equipment – See section "A". What do you need to safely fill and drain your tank? Oil mix bottle? Storage tank sizes?
Fuel filter – Unfortunately, the fuel filters that auto stores stock are not very good quality. Here is some helpful advice.
Fuel mixed? – Is there oil in the gasoline?
Fuel system leaks – A rare but annoying problem
Fuel system test – A quick and easy way to tell if the system is functioning properly.
Fuel tank leaks – How to fix factory defects.
Harness adjustment – This is for the Miniplane Top 80 but works for most other harnesses.
Harness strap repair – Thin, tall pilots routinely experience buckle breakage on some harness models. Here is an easy fix for the problem.
Leaks, oil – The Top 80 leak page can help you identify where the leak is coming from and what type of leak it is.
Mounts, engine – Mounts must be checked often. If you replace them with the Viking mounts, do not make the mistake this pilot made.
Oil leaks – see "Leaks, oil" above
Overheating – This will destroy an engine. What causes it? How is it prevented?
Performance issues – Does your engine run poorly, if at all? This page can help.
Performance tuning – Most paramotors run poorly in the midrange, the range that we spend most of our time flying in.
Piston ring – How to tell if the ring needs replacement
Priming a paramotor – see "Starting a paramotor" below
Propeller hub removal & installation – how to get it off and on
Propeller Info – General information including how to correctly attach and repair it.
Rebuilding 2-cycle engines – When is it time? This general and helpful article
from Utah Motor Trails can help you decide and gives the basics on how
to do it. The wrist/gudgeon pin in a well-taken care of Top 80 may be the first part to fail. It would save cost if just the pin was available and
it could be replaced along with the bearing and circlips, but this is not possible. The complete piston assembly must be purchased. Here are some
good tips from MCB Performance on rebuilding two-stroke engines.
Reed valves – Info on how to check them and replace them, if necessary
Sidestick mount protection – The sidebars and sidestick mounts will grind away on each other. Here is a fix.
Smoke systems – Pilots must be extremely cautious when installing smoke systems on any 2 cycle engine with a tuned exhaust and here is why.
Spark plug info – Meaning of the NGK part number
Spark plug cap replacement – It is not that simple if you want it to last and work well.
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.
Tools – Paramotor essential tool kitTorque Values – This is the Top 80 specification page which has a thorough torque section. Hit "page down" twice to see it.
Tune-up – Here is how to tune up the Walbro carburetor
Walbro WG-8 carburetor – This info can also be helpful for other models that have a fixed main jet.
Walbro WB-37 carburetor – This info can also be helpful for other models that have an adjustable main jet.
