Hi guys,

i have also a new YS 60SR with 12 flights now.

Today, the engine runs abrupt lean. Damn ..... after a autorotation i checked the engine.
The engine was all right, but the glow plug was broken. The engine runs now with a rich carburator setting (and new OS 8) still lean.

I think the check valve was damaged. I replaced it and tomorrow i will take a new test flight.

Happy New Year!

Hi,

pressure is now OK! But the engine runs still lean.
IMO the cause of the lean run is definitively the carburator.

Now i order a new OS 55 HZ-R + OS Powerboost Pipe II Limited Edition!
I had never any issues with my other OS HZ-Rs.

Hi,

after cleaning from the carburator, the YS 60SR runs very well.

No comment....




P.S.: I'd used a fuel filter!

Is that an insect? Probably crawled in the open carb from the fan shroud pretty easily. Little bastard!

I'm not sure. Maybe it was a nitro junkie bee from japan.
