Of course, it's always good to read and follow the manual.
That said, it's also important to use good brand of motor
oil. For whatever reasons, the cheap oils don't run well in
air cooled engines.

My fav is Castrol, but other folks have had good experience
with other oils. I think anyone using other than castrol is
an impolite person who lacks graces. Let the flame wars
begin!

_MANY_ years ago (like 50 or so) many small 4-cycle engines

recommend non-detergent oils, but that has been so long ago
there are
precious few if any still running outside a collector's
