RE: JetJoe OWNERS thread
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.
