An email is sent to tower hobbies, but I dont think this will help
They dont sell the engine anymore and it is bought in Norway
But it is worth a little try
I found this :
http://www3.towerhobbies.com/cgi-bin...XMW56&P=PU. In the middle of this site its written a comment about os 91 fx, and what that is needed ifI buya newneedle valve assembly(backplate and bracket)
I guess its this I eventually need.If I dont get it free, I guess Ill try to cut off the needle valv eassembly first, and mount it on the front of the fuselage
