Set parking brake ON
Set the carburetor heat control in the full COLD position
Select the desired tank with fuel selector valve.
Starting Engine when cold:
Open Throttle approximately ¼ inch.
Turn the master switch ON
Turn the electric fuel pump ON.
Move the mixture control to FULL RICHEngage the starter by rotating magneto switch clock wise and pressing in.
When the engine fires, fires, advance throttle to desired, setting. If the engine does no fire within five to ten seconds, disengage starter and primer with one to three strokes of the priming pump. Repeat starting procedure.
Starting engine when hot:
Open Throttle approximately ½ inch.
Turn themaster switch ON
Turn the electric fuel pump ON
Put mixture control in IDLE CUT-OFF
Engage the starter by rotating magneto switch clockwise and pressing in. When the engine fires, advance the mixture control and move the throttle to desired setting.
Fuel – on proper tank
Electric fuel pump – ON
Engine gauges – checked

The best rate of climb at gross wight will be obtained at 85 MPH. The best angle of climb may be obtained at 74 MPH. At lighter than gross weight these speeds are reduced somewhat. For climbing enroute a speed of 100 MPH isrecommended. This will produce better forward speed an increased visibility over the nose during the climb.
The cruising speed is determined by many factors including power setting, altitude, temperature, loading and equipment installed on the aiplane.
The normal crusing power is 75% os the rated horsepower of the engine. Ture Airspeeds which may be obtained at various altitudes.The mixtures and power settings can be determined from the charts in section IV of this handbook.
Use of the mixture control in crusing flight reduces fuel consumption signicantly, especially at higher altitudes. The mixture should be leaned during cruising operation above 5000 feet altitude and at pilot´s discretion at lower altitudes when 75% power or less is being used. If any doubt existsas to the amount of power being used, the mixture should be in the FULL RICH position for all operations under 5000 feet.
To lean the mixture pull the mixture control until the engine becomes rough, indicating that the lean mixture limit has been reached in the leaner cylinders. The enrich the mixture by pushing the control towards the instrumnet panel until engine operation becomes smooth.Ih the airplane is equipped with the optional exhaust gas temperature (EGT) gauge, a more accurate; refer to AVCO lycoming operator´s manual.
In order to keep the airplanein best lateral trim during cruising flight, the fuel should be used alternately from each tank. It is recommended that one tank be used for one hour after takeoff, then the other tank be used for two hours, the return to thefirst tank, which will were full at take-off. The second tank will contain approximately one half hour of fuel. Do not run tanks completely dry in flight.
Before landing checklist:
Fuel-on proper tank
Electric fuel pump – ON
Mixture – SET
Flaps – SET (115 MPH MAX)
At the pilot’s discretion, the flaps should be raisedand the electric fuel pump turned off. After parking, the radios should be turned off and the engine stopped by pulling the mixture control to idle cut-off. The throttle should be left full aft to avoid engine vibration while stopping. Then the magneto and master switches should be turned off and the parking brake set.
The most common cause of engine power loss is...
