Follow the recommendations in the POH. 

At power settings where MP is above 23″ (top of the green), always run mixture and RPM full forward. 

Reduce power into the green before reaching 1000 ft AGL. 

During climb mixture should be full rich until reaching 3000 feet (POH).  Climbing at higher airspeeds improves engine cooling and forward visibility – and you could even get to your destination more quickly. 

Cowl flaps must be open for taxi, take-off and climb. 

Add power ‘right to left’:  first enrich the mixture, then increase propeller speed, finally add power (and open cowl flaps when going to climb power). 

Reduce power ‘left to right’:  first reduce power, then reduce propeller speed, finally adjust the mixture (and close cowl flaps when transitioning from climb to cruise). 

Only lean when MP and RPM are in the green.  Then lean at a rate of a half turn per 15 seconds.  Obtain peak EGT then enrich by at least 50°F EGT. 

Before entering the pattern, or upon reaching the FAF, enrich the mixture, lower the gear and make sure the fuel selector in on ‘Both’.  It is permissible to postpone setting the RPM to high until power is further reduced (see the next item) 

To reduce power below the green MP range, pull carb heat; pull the throttle and push the propeller control all the way in (remember `left-to-right’?). 

When a go around or missed approach is initiated, push mixture, prop control, and throttle in (`right-to-left’!) when a climb has been established, open cowl flaps.  Finally deal with flaps. 

Don’t ever lean just a bit when taxiing: you may forget to enrich before takeoff and that can ruin your day.  Don’t lean at all or lean aggressively — on the ground. 

Never allow CHT to get above 400 °F 

Avoid running at low RPM and high power.  Never, ever lower RPM when the manifold pressure is above the green arc.
