Saito 40

Every once and a while my saito 40 stops in mid flight. Five minutes into
the flight it stops dead.
When I restarted it about ten minutes later I had to turn the engine over
several revs with the electric starter. Usually it would start on the first
rev when restarting after finishing a flight.
I presume Im doing something wrong.
Does anybody have any idea what.
Thank you
Carl Anderson.

"stops in mid flight" "When I restarted it about ten minutes later I had
to turn the engine over several revs with the electric starter. Usually it
would start on the first
rev when restarting " Indicates the motor the motor has leaned out in
flight, got hot and used/dried out all fuel remaining in crankcase.
Try taking off a click or two richer on the needle valve or checking for air
leaks especially if using a Du-Bro or similar fuelling valve. Fuelling valve
may have a stuck shuttle or need new "O" rings which should be replaced each
year or two - especially if stored for any length of time and dried out.

Personally, I don't know anything :-) But from
<http://www.mecoa.com/faq/fuel/tank.htm>

> The main cause of an engine dying half way through the flight is usually a pin hole in the fuel line inside the tank.


Check out the rest of the K&B/MECOA site about engines - lots of good
info there. <http://www.mecoa.com/faq/index.htm>

My Saito .40 was leaning out, but not quitting. I could tell something was
wrong and quickly brought the plane back down. The culprit was a small
plastic shaving caught in the carb. spray bar. Don't know how it got in
there. I use an inline fuel filter.

(snip)
I had 2 of these engines years ago and a similar problem with one of them.
Turned out that the intake tube has a rubber O-ring where it fits into the
cylinder and it was not in far enough to seal properly. I had to do a little
filing down where the carb and intake tube are screwed on to tilt the tube
into the head a little more.
