5. for measuring the point at which the pop off pressure is achieved The tool is available from the distributor shop The height of the lever upon which the spring acts is also critical and should be 0 5 0 7 mm above the body of the carburettor The adjustment of the fuel lever and fuel spring is a very delicate operation involving fragile components and should only be undertaken by an expert The carburettors fuel filter is also located here and can become blocked with rubbish causing a loss of power which is especially prevalent at high rpm s Pay attention please The diaphragm carburettor pumps thanks to the variable pressure inside the crank case The pressure comes to carburettor throught a small hole on the reed valves we suggest you to control and clean that hole and the nearest gaskets You can use a 2 5 mm drill bit clean the back side of the hole The typical symptom of this defect is an engine that hauls in the final part of the throttle control means that the carburettor is unable to pump enough fuel at high rpm last update 23 10 2012 7 TROUBLESHOOTING RUNNING IN gt You must run in the engine before flying gt Donotrev up for five minutes while running in gt Therunning in is over after consuming 10 litters of gas gt The lifespan of your engine can double with a proper running in while with a bad done you may damage it since the very first hours of working gt While on the en
