Saito 40

"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.

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

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.
