I have never seen that difference between the one piece and two piece cones from the engines that I have ran.
To set the fact straight to motor Sean is referring to is Direct from Joe to Myself then to Luis/Sean.
If the Engine is assembled correctly you will have absolutely no problems in changing the glow plug, Did this engine come from Andy or did you buy it Direct? I would not suggest using 2 Stroke oil however, If you noticed PST will not even warranty a motor that has been ran on 2 stroke oil. I run 5% oil here on all my Jet Joes and my original engine that I received is past the 350 minute mark and still ticking along.

I have Talked to Gasper in the past and you can "Degauss" the RPM Sensor all you want but FADEC version doesn't require it nor will it work any good on it.
The Issue on the engine with Sean/Luis can be a couple of different things with the electronics but we won't know for sure until it reaches my door step so we can evaluate the situation.

Greg,
Your problem with the low speed error and the engine shutting down on decel could very possibly be the Deceleration Delay being to low, try increasing this value a couple of marks and give it another go.
I'm sorry, but that's incorrect. My own JJ, right from the factory, has the same issues with the CC moving when the glow plug is removed. It's assembled correctly. It's a pain when you change the plug.
The original plug is worthless, too, just pitch it over your left shoulder and install an MC-9.
Another thing that is incorrect, if you have a magnetic sensor, it may need degaussing, it has nothing to do with the ECU at all.
I had that before with a RAM and Carlos Villareal set me straight with a phone call while I was at the field a few years ago, call it Voodoo, but it worked. Have done it again several times with other people's engines, and the old RAM fans all seem to know this trick, I sure didn't invent it.
2 stroke oil, I think WREN says it's fine, but you can check their website.
