Rotax 185 aircraft engine fuel and oil recommendations.

RECOMMENDATION

Normal carburetor settings with Fuel/Oil Mixture at 30-1  or 35-1. 
High Speed Needle-3/4 to 1 open. 
Low Speed Needle-1/2 to 3/4 open.

NOTE - If low speed needle is adjusted too lean the engine will bog down or hesitate when accelerating from idle. 

If high speed needle is set too lean full engine R.P.M. will not be obtained and possible overheating could occur. 

The above settings are normal settings, and you should not move them more than an 1/8th of a turn at a time in or out as required.) You should end up with the needles in the above specification ranges.

Turning the needles clockwise LEANS the mixture.

Turning the needles anti-clockwise RICHENS THE MIXTURE. 

Cl)-          Warm up engine, (2 to 3 minutes at 2000 - 3000 R.P.M.) before take off. Do the same after landing. This procedure helps stabilize engine parts and temperatures.

C2)-         At regular intervals do a "nuts and bolts" tightening job on your aircraft, including the engine.

C3)-     Check the fuel tank and fuel lines regularly for dirt and water, Also for any signs or damage.

REMEMBER -          A little time spent on maintenance on the ground will give you more than double enjoyable time in the air.
