Minari 180 & 200

updated January 22, 2021

Warning for electric start models – DO NOT USE THE 14.8V LIPO BATTERY!  IT WILL BURN OUT THE STARTER.  USE ONLY A 12V LIPO.

All Italian paramotors use many of the same parts e.g. ignition system, carburetor, starter, throttle cable, engine & muffler mounts, spark plugs, among others.  If you do find what you are looking for here, check the Top 80 and Polini pages.

SPECIFICATONS – important info including maintenance intervals and torque values

Air box – the air box usually has an internal air filter.  It must *NOT* be saturated with oil.  It is unnecessary and can restrict air flow into the engine.  Periodically wash the filter in hot soapy water.

Air filter – see "Air box" above

Bearing condition – What condition are the bearings in my engine?  Which one is the most likely to fail first?

Bearing replacement and case disassembly/assembly – Here is how to replace the main crankshaft bearings and seals

Belt adjustment & diagnostics – redrive pulley misalignment is the main cause of redrive belt failure

Breaking in the engine

Carburetor info - Walbro WB general information including troubleshooting and repair

Carburetor adjustment – Minari has particular settings for the idle, low, and high speed adjustments

CHT – see "Cylinder head temperature gauge" below

Crankcase assembly/disassembly – see "Bearing replacement and case assembly" above

Clutch bearing replacement – It is done in the same manner as for the main bearings (see Bearing replacement... above).  Steel does not expand as much as aluminum so a press must be used to install the clutch bearings.  They will not just "clink" into place.

Clutch maintenance and repair – see the "User manual" and, in particular, "Rebuilding a paramotor" below

Cold weather operations

Crankcase assembly/disassembly – see "Bearing replacement and crankcase assembly/disassembly" above

Crankshaft replacement – see "Rebuilding a paramotor" below.  The paramotor must be completely disassembled.

Cooling shroud – it dramatically lowers the engine running temperature

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....  An exhaust temperature gauge (EGT) is only better because of its quick response.  It is rarely needed on a paramotor because changes in the air/fuel mixture are harder to do than, for example, on float-type carburetor in a general aviation aircraft.

De-carbonizing a two stroke engine – Alex Varv shows how to do it without removing the cylinder.  However, I do not recommend using any sealant between the cylinder and cylinder head.  I have never had a  head leak when the "O" ring is new and installed properly.  The exhaust port should also be cleaned at the same time.

Decompression port check – Here is an easy, simple way to check whether the port is clogged or not.

Decompression port cleaning – It must be clear.  Failure to keep it free of combustion deposits will shorten the life of the starter.

Drips – Two stroke engine carburetors drip/leak fuel by design.  It cannot be helped.

Electrical troubleshooting – see "Ignition troubleshooting" below

Emergency engine kill system – see "Kill system, alternate" below

Engine leaks – see "Leaks of the engine, exhaust, and redrive" below

Engine stall – see "Stall" below

Flywheel removal and installation

Four cycling – see "Performance tuning" below

Fuel & oil specifications – 2.5% (40:1) full synthetic oil e.g. AMSOIL Dominator or Motul 710 with premium 100% unleaded.

Fuel filter – What kind/type to use?  If you choose poorly, the engine will also run poorly, if at all.  Removal and installation tips.  The fuel system MUST be purged of old fuel and air when changing out the fuel filter!

Fuel line size/installation – these are IMPORTANT notes that will prevent engine fuel starvation

Fuel system leaks

Fuel system modification – the FSM dramatically fixes fuel starvation and most performance issues (still in the test phase)

Ignition coil secondary wire replacement – This is the most common point of failure in the ignition system

Ignition timing – see "Timing" below

Ignition troubleshooting - including the newer Minari's which have the magneto ignition system

Kill switch problems

Kill system, alternate – The inability to shut down a runaway engine could be exceedingly dangerous especially with the Minari 180/200.  This alternate system routes a cord from the spark plug boot to some accessible place.  Yanking the cord removes the source of ignition to the spark plug.  The engine will stop!

Leaks of the engine, exhaust, and redrive – The Top 80 leak page can help you identify where the leak is coming from and what type of leak it is.

Manuals – see "User manuals" below

Midrange roughness & "four cycling" – see "Performance tuning" below

Mounts, rubber (engine) – Here is a way to quickly check them.  These are normal consumable parts that fail with use.  Pilots must keep an eye on them and replace them regularly.

Owners manual – see "Users manual" below

Parts diagram – note that these diagrams can have changes as the factory makes improvements on their engines

Performance tuning – Most paramotors run poorly in the midrange due to a rich air/fuel mixture, the range that we spend most of our time flying in.

Piston failure – Madsen's (a chainsaw dealer) gives the various ways a piston gets destroyed with some info on the causes.  Paramotors are more like chainsaws than any other engine.  In fact, paramotors use carburetors from obsolete chainsaw engines.

Preheat system of air entering the carburetor

Priming a paramotor – Because the Minari has a vertical carburetor it is particularly sensitive to flooding from over-priming.  3-4 seconds is all that is needed.

Propeller hub info, removal, & installation – this page is particularly about the Top 80 but has important information relevant to the all hubs, especially vibration sources.

Propeller info – General information including how to correctly attach and repair it

Purging the system of fuel – It must be done if a paramotor is to be stored for more than a few weeks, especially if you are using ethanol fuels.

Rebuilding a paramotor – includes disassembly and assembly of the major parts of the engine e.g. flywheel, cooling fan, clutch, carburetor, etc.

Redrive belt adjustment & diagnostics – see "Belt adjustment & diagnostics" above

Reed valve – if the petals get weak, chip, or break into pieces the engine will not achieve full power or may not run or start.

Rich running condition – see "Performance tuning" above

RTV – e.g. Permatex Blue or Ultra Grey.  Used to seal case halves, some gaskets, and surfaces.  Apply with a clean finger.  Forget the spout that comes with the tube.  It is useless.  Use Ultra Grey for sealing surfaces that may become hot, like the exhaust flange gasket.  More sealant is not better.  It is not as simple as most think.

Safety net installation – on NEW Miniplanes the safety net comes already assembled and ready to install but not replacement netting kits

Safety net replacement – replacement safety netting from Miniplane must be assembled.  Here is help to prepare the net for installation (above).

Safety net wear – How to minimize wear and tear on the safety net

Shroud, cooling – see "Cooling shroud" above

Spark plug installation – Do not waste time troubleshooting an engine unless the spark plug is new.  It must be gapped and installed correctly.

Spark plug type and gap – see "SPECIFICATIONS" below

SPECIFICATONS – important info including maintenance intervals and torque values

Squish – Pilots must get the correct size cylinder gasket to prevent overheating, detonation (knock), and engine damage.

Stall – Going to full throttle, the engine stalls!  What happened?

Starter, manual – like the Polini's, the Minari's also have problems with their starters.  See the Thor Flash page for some maintenance notes.  Getting the electric starter seems to be the only long term solution at this time.

Starter, electric – some pilots have had the best results with a 12V LiPo battery, 50% charge, and a 40A fuse.  A properly primed engine will start immediately.

Throttle cable – Cleaning, lubrication, modifications, and cruise control info

Throttle placement in the hand while launching a paramotor (Miniplane throttle)

Timing – how to both check and set the timing of a paramotor

User manual – from Minari   The English section begins at page 15.  This manual has basic information including torque values.

Vibration – see "Propeller hub info, removal, & installation" above

Warming up – when is a paramotor warmed up sufficiently and ready to fly?  When the cylinder head temperature reaches 70-80ºC, the fuel/air mixture is sufficiently hot enough to ensure that it is 100% vaporized and that the engine will not be fuel starved and potentially overheat.  Overheating can happen very quickly!
