582 Power Issue??

[tx_swordguy]

when you shut it off after its warm do a mag check before you shut down. It could be a bad pickup coil. I had a similar problem on a gyro with a 582. I noticed a fluctuating rpm in the air and it would shut off (when I was shutting down)on only one mag after it was hot. What was happening was the pickup coil was not totally crapping out. cold it would work but once it was hot the electronics would break down and not work right. Therefore I was only getting rpms off one side and occasionally the other and that was why I was getting fluctuating rpms. You can ohm the pickup coils without taking them out. I don't remember for sure the numbers but I think the old style in the 80-90 range and new style in the 140ish range. (search testing rotax pickup coils)

The foreign material on the screen was telling you there may be a fuel issue causing your problem. Is there another fuel filter in the system?

Has car gas been used in the tanks? Ethanol dissolving some of the resin in the tanks?
