Hi,

I have a RCS180 which has just been broken in. When it is warm, the engine tends to run only about 3-4 seconds after being fired up. When it can run (after say 10 start attempts), it can run pretty decent on the ground (8200 RPM on Menz 18X6). In the air though, it has the tendency to lean out.

The first flight (i.e. when the engine starts cold) is always good (easy to start and no lean out in the air).

The ignition battery (4 cell 1100 mAH sanyo) is pretty new and checked OK. The ignition switch is the heavyduty MPI name-brand.

Any suggestion on the cause of the problem?


Thanks QC
