before installing rear end cap course provided decibel-reducing action Attachment somewhat crude must admit wire wrapped around engine-muffler assembly best could come up However later project found easier professional solution add-on muffler problem fly stunt models large props turn 10000 rpm range considerably reduces engines sound output muffler decibel output below AMA-recommended maximum model club field rules require mufflers engines larger 06 borrowed simple one-piece muffler design first saw use George Ehnot Sharon PA Skylarks made rectangular aluminum bar stock numerous holes drilled through exhaust outflow Georges muffler used holes same diameter found holes several sizes made good sound attenuation minimizing exhaust restriction porting pre-muffler era model engines designed unrestricted exhaust outflow time time Im asked about converting older engine Schnuerle porting supposition seems its possible improve power output significantly merely grinding groove two lower cylinder bore cross-scavenged model engine Thats true Yes modern Schnuerle-type engines put out power average cross scavenged sort thats mainly because Schnuerle s flat-topped piston lighter baffle-top thus wasting less energy starting stopping top bottom stroke permits efficient combustion chamber shape Two-stroke engine operation depends upon being able exhaust burned fuel supply fresh fuel-air charge cylinderboth same time maximum efficiency fresh charge must somehow directed upper cylinder exhaust rushes out bottom Cross-scavenged engines deflecting new mixture away exhaust outflow means baffle piston crown Schnuerle engines 360a porting types too accomplish same objective bypass ports shaped control inflow direction Achieving art science requires considerable trial-anderror experimentation Id say would nearly impossible average modeler improve performance individual engine reworking its cylinder porting However thats say cannot done have enough spare parts

odd because model engine makers want have satisfied customers possible Instruction sheets cost manufacturer time money prepare purpose help buyer get maximum satisfaction his/her purchase True some cautionary material provided prevent engine maker being sued Never attempt starting engine hand-flipping propeller example Yet valuable operational instructions well ignoring can cause considerable trouble instance advice model diesel instruction sheets use electric starter has valid reason behind instructions dont detail think should model diesel engines installed usual upright position will accumulate least small quantity liquid fuel crankeases during starting procedure presents no serious problems during handflipping However electric starter theres distinct possibility enough liquid fuel can flung upward combustion chamber hydraulic lock occur head space above model diesels piston approaches postcard thickness during cold starting doesnt take much liquid incompressible fuel fill tiny space does high-torque electric starter spinning prop happens broken shaft bent rod deformed wristpin and/or damaged piston certain occur Thats advise model engine users read instructions pay attention what tell Yeah model engines pretty much alike says model flier know run know run em Modelers attitude probably good model engine industry spend money repairs replacement engines read
