●Prop-recommendation:Mejzlik-26x12.
●Use15:1fuel:oilratioforbreak-in.
●NevermakethefuelmixtureleanduringBreak-in.Itcouldcauseseizureevenduringidlingor

●Starttheengineafteradjustingtheneedletothefollowingreferencevalue.
●Mainneedle：Approx.2.5~3turnsCCWfromfullyclosed
●Slowneedle：Approx.4turnsCCWfromfullyclosed(Thenthrottleshouldbefullyclosed)
●Actually,thebestpositionoftheneedlesvarydependingontheprop,temperature,humidityandso

◇Peakadjustment
●Afterstartingtheengine,warmupforapprox.30secondsatlowspeed.
●Achievethepeakatfullthrottle.
→TurnthemainneedleCWgraduallytothepositionwheretheRPMisgreatest(thepeak).ContinuingtoturntheneedleCWpastthepeak

◇SlowneedleAdjustment
●AfterachievingpeakRPM,nextisslowneedleadjustment.OpenthethrottlefromlowRPMtofullthrottlequickly.
●TurntheslowneedleCCWslightlyiftheenginehesitatesforamomentorstallsbeforetheenginereachesmaxRPMbecausethemixtureis

●TurntheslowneedleCWslightlyiftheengineisslowtoreachpeakRPM(fullthrottleset)becausethemixtureistoorich.
●AdjusttheslowneedleasaboveuntiltheRPMfollowsthethrottlemovementsmoothly.Theimportantpointistoadjusttheslowneedle
AFTERthemainneedlehasbeenadjustedtoitspeak.
●Nowbreak-inatgroundlevelisdone.Adjusttappetsbythemethoddescribedlater.
◇Pre-flight/Flightadjustment
●Whentheslowneedleadjustmentisdone,checktheresponsebyrevvingupfromlowspeedtofullthrottlequicklyseveraltimes.
●OpenthethrottlefullyandturnthemainneedleCCWapprox.60〜90degreesfromthepeakposition.Thisistomakethefuelmixturericher
