I know that suggesting a person make an actual phone call is absurd in the year 2009, but, Hobby People is the retail arm of Global Hobby and they likely have the parts you need. Global Hobby is the US importer of Magnum engines.
Most likely this is the assembly you need and it is ten dollars

I already ordered a needle assy from them last night. Thanks for the link though and for letting me know we still have phones.
For the others that helped without being sarcastic thanks again.
