Let me fire that RIGHT back at you. It does help knowing what you are talking about before taking shots at others.
Mine, and at least several other people's engines, have the same "problem" with the plug hole not lining up. Since I did not assemble or dissasemble the engine...the factory did...there are one of two possible scenarios here...either the factory is assembling them wrong...or it is as they are designed.
Secondup...if you have a magnetic sensor, and you are getting funky RPM readings...you look at the SENSOR first. It's a magnetic sensor, with a magnet in the spinner, and I'm sorry, but magnets CAN lose their magnetism, and sensors CAN be tricked by electrically charged parts, and given a solid state piece of electronics like the Gaspar ECU, I would look at the sensor first.
Who mounted the sensor? The factory?
Always check the guage or sensor first.
Are the RF supression capacitors on the starter motor?
I am VERY surprised, in that I thought this engine was bought through "Jetjoe USA", who have vast experience servicing these, and that it would have been test run and debugged like the UK rep does.
What about
Dont know why but...I'll reply....
lets start with the CC...."either the factory is assembling them wrong...or it is as they are designed." Well, little of both! The twist the CC does when the plug is removed is caused by the fuel and propane feed tubes and how they are aligned between the CC and the diffuser, slighly offset. It is absolutely possible, during assembly, to adjust this offset to eliminate the CC from rotating in the can when the plug is removed. I have, unlike ET, broken down and reassembled the JJ several times and speak from first hand knowledge.
As for the RPM sensor... "I'm sorry, but magnets CAN lose their magnetism, and sensors CAN be tricked by electrically charged parts, and given a solid state piece of electronics like the Gaspar ECU, I would look at the sensor first." What does this have to do with the cost of bread??
The discussion was over degaussing, my reply was that degaussing does nothing for a Gaspar FADEC rpm sensor. Funny how you either ignore posts or twist things every time your errors are corrected....
While I NEVER claim to be an expert at anything, what I do convey is always from actual experience with a product. Since I do speak to Gaspar several times a week and I have been fairly well schooled by the FADEC ( and Merlin) designer in addition to servicing his turbines, I think I would at least pass your stringent qualification requirements... As I said, I'm done. Good luck guys...
