Minari 180 & 200

by Had Robinson

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

Note: Here are some basics on the Minari paramotor.  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

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

Bearing replacement and case assembly

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

Breaking in the engine

Carburetor info - Walbro WB-37 information, adjustment, & repair

Carburetor adjustment

Case assembly – see "Bearing replacement and case assembly" above

Clutch maintenance and repair – see the "User manual" below

Cold weather operations – Unfortunately, the WG-8 and the WB-37 are very sensitive to both high altitude and/or cold weather operations.

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.

Engine stall – see "Stalling" below

Fuel/oil specifications – 2.5% (40:1) full or semi-synthetic oil with premium MOGAS or AVGAS

Fuel system quick test – See the "Quick fuel system test" in section A of the link

Fuel system test – A more thorough test of the fuel system

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

Kill switch system – The Italians have notoriously poor quality control and a failure of the kill switch could be exceedingly dangerous with any
     engine, especially the Minari 180/200.  Be sure to install an independent system to kill the engine.  Routing a cord from the spark plug boot
     to some accessible place and then yanking the cord works well by removing the source of ignition to the plug.  The engine will stop!

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.

Performance tuning – Most paramotors run poorly in the midrange, the range that we spend most of our time flying in

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 upper connecting rod bearing in a well-taken care of engine will likely be the first part to fail.  Here are some good tips from MCB
     Performance on rebuilding two-stroke engines.  Splitting open the engine case is a technical job and requires special tools that will not
     destroy the case halves.  Go to this page for information on how to remove and re-install bearings and the correct way to seal the case halves.

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

Safety net installation – on NEW Miniplanes the safety net comes already assembled and ready to install

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

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.

Stalling – Snapping the throttle open in 1/2 second or less will always stall the engine, especially clutched engines, no matter how accurately the
     LS needle is adjusted.  It takes about 1.5 seconds to open the throttle fully without causing stall.  Keep this mind when launching.

Starter – like the Polini's, the Minari's also have problems with their starters.  We are working on fixes.  See the Thor Flash page for some maintenance notes.  It seems getting the electric starter is the only long term solution at this time.

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

Timing – This page tells you how to time an engine.

User manual – from Minari  The English section begins at page 15.

Weight – 24.3 kg (53.5 lb) all up weight at take-off minus fuel (the 200 weighs a bit more)
