Hello Eric,
I think there is a misunderstanding here, let me try to explain: Jet Central has never sold parts for any engine, we sell full assembled units, not parts, and we have never been involved with the design, manufacturing, servicing or marketing the JG100 engine.
I'm sorry but we can't help you with your engine because we do not have any parts for it.
If you have any questions, please do not hesitate to contact us.
Best regards
Felipe
