3. Remember that once the engine is warm, hot air with a low fuel/air ratio will be in
the crankcase, this may lead to reduced maximum revs when the engine is hot and a
weaker mixture, needing a slight richening of the needles to avoid an overlean
condition.
4. Although the carb has a pump, it is good practice to ensure that the tank centre-
line is on, near and close to the carburettor centre-line.
Routine Maintenance
With a new motor, you will it necessary to check the valve clearance more often than
normal, this is because the valve mechanism is undergoing the running- in process,
and the cams, pushrods and rockers are still to bed in.
If the motor does not run for a while, oil can gather in the lower cylinders, turning the
engine over a few times will normally remove this.
Take care when removing the plug caps they should be gently levered off vertically,
do'nt twist them back and forth, this will cause damage to plug and cap. When
replacing, ensure the caps go on with a double click. The plug gap should be 0,3-0,4
mm, this is factory set.
Periodically check the tightness of all EXTERNAL nuts and bolts, do'nt overtighten.
Before each days flying, do'nt forget to lightly oil the valve gear.
If fitting a cowling, you may find it necessary to baffle with balsa or light ply between
the cylinders to ensure the air passes through the fins.
Due to us having no control over the use and operation of this motor, MOKI Modell
Kft. and its agents accept no liability for damage caused to persons or property.
