STARTING ENGINE
EngineMaintenance
Alwayschecktheenginemountingbolts,muffler,glowplug,propellerand
spinner,etc., beforeattemptingtostarttheengine.Checkforloosebolts,
nuts or screwswhich maycome off whenthe engine is runningandcause
seriousdamage.Alwayschecktheareainwhichyouwillbeflyingorjust
runningtheengine.Checkfor possiblehazards,suchas looserags,
rocks,tools,etc., lyingonthegroundwhichmay getcaughtintheprop.
Ifyou intendonstartingtheenginebyhandflippingtheprop,always use
achickenstick,andbesureto checkthepositionof theprop.It ismost

POSSIBLE CAUSE
Glowplugbatteryismakingpoorcontact.
Batteryisdeadorhasa very lowvoltage.
Badglowplug(burnedupordeteriorated
filament).
Improperair/fuelmixtureintake.
Engineisfloodedwithfuel.
Enginemaybeflooded.
Fuelisnotreachingthecarburetor.
Improperbreak-inprocedures.
Looseplugorbadplug.
5.Turn the radio on and open the throttleto fullopen Place yourfinger
overthe airintake on the carburetorwhile turning the prop counter
clockwise a fewtime?Noticethe fuelline Itnofuelisreaching the
carburetor,recheck the fuelline plumbing
6.Reduce the throttleto1/4or 1/2throttleforstalling
7.Usinga starting stick (chicken stick)and holding thefuselagefirmly,
quickly flipthe prop in the counter clockwisedirectionDonot attach
the glow plug clip in this step This will prevent the engine from being
floodedand willmake startingmuch easierDo not use bare hands/
fingersforstarting, as the kick back froma model enginecan be
strong enough to cause severeinjury
8.Attach the glow plug clip at thistime
9.With quickflipping movements,flipthe prop inthecounter-clockwise
direction Ifthe engine doesnot tryto startinthe firstfewtries,double
check your procedure and keep trying
10.Once the engine has started,listen carefullyto the sound ofthe
engine The sound of the engine willtellyouhow the engine is
running, if you know what to listen for A lower tone, popping sound
is the sound of a rich running engine Asyouturnthe needle valve
in,the popping sounds shoulddecrease and thepitchofthe engine
should rise The optimumneedle valve settingwill depend on your
engine. Again checkwiththe manufacturer'srecommendationsfor
engine break in procedures and valvesettings
