A couple of questions about the parts list:
You said you needed 11617535849 x4 Screw 50x20. Tischer has a complete conversion kit available, and they only supply 2 of these. Any idea why you needed 4?
Also, you didn't list 11617559530 vent hose. Did you not need that?
Also, do you know the torque values for the various parts (especially the manifold itself), and the torquing sequence for the manifold?
Thanks.
Cheers!
