Winterizing your Paramotor by Alex Varv


Paramotor Winterizing

2011-Dec-11 by Alex Varv

For many, cold weather means hibernation. But your motor needs some preparation to avoid problems come spring. It will appreciate some TLC and treat you better. These tips, from long-time two-stroke expert Alex Varv (www.Aerocorsair.com) will help.

1) Fuel system:

  • Start engine, warm-up, disconnect the fuel line from the carburetor, start the engine and run the carburetor completely dry; this way you will prevent gum-up; if your membranes are over one year old, better overhaul the whole carburetor.
  • Empty fuel tank and check the pick-up line for stiffness, cracks and make sure all the connections are sound and protected with at least cable ties
  • Clean the in-tank check valve with filter if you have one (you should have one)
  • Clean the in-line fuel filter or simply replace it

2) Electrical system:

  • Check all cables for damaged insulation, repair/replace and anchor them to prevent excessive vibration which may rupture the cable by connectors.
  • Check spark plug cap/high voltage cable for unrestricted continuity, clean any black powder or replace spark plug cap
  • If you have a battery, check torque on the positive and negative post screws an if loose, remove screws, use LO strength Locktite and re torque
  • Connect battery to a battery tender (you can leave it connected all the time

3) Mechanical:

  • Loosen propeller bolts especially if you have a wooden propeller and store the propeller in a horizontal position
  • Remove belt, clean rubber cake from the reduction pulley grooves
  • Check big pulley for play on shaft or bearings and repair
  • Check play on the main bearings (crankshaft bearings) by pushing in and pulling out the small reduction pulley
  • Overhaul carburetor if membranes are over one year old
  • Inspect reed valve for damaged petals
  • Tighten all the bolts and nuts on engine according to specs
  • Lubricate electric starter Bendix shaft
  • Lubricate ball joints (male and female) of exhaust manifold and tuned pipe (antiseize compound or HI Temp Hondabond)
  • Lubricate tuned pipe end and muffler flange connection (anti seize compound or Hi temp Hondabond/Yamabond)
  • Cover exterior of reduction belt and all rubber mounts (engine and exhaust) with Armorall to prevent cracking

4) Cage/Frame:

  • Check fuel tank connection to the frame (bolt or Velcro)
  • Check any worn Velcro if existing
  • Check for loose or broken strings on the cage
  • Replace any bent tubes on frame or cage

5) Harness:

  • Check all stitches
  • Check all straps for wear and tear, repair or replace

6) Internal engine protection:

  • Remove spark plug
  • Pour one spoonful of two stroke oil into combustion chamber when the piston is down (or fog the engine with a special oil available at boat stores)
  • Move piston up and down a few times
  • Install spark plug
  • Once a month, move the piston up and down (by turning the propeller clockwise and counterclockwise. (It has been suggested that this step may do more harm than good)

7) Parts replacement:

  • - if you noticed any worn parts, now is the time to repair or replace them

These instructions will help make your paramotor ready when spring arrives.
