This particular model has the needle valve mounted on an appendage to the back plate, and the appendage was broken off from the back plate in the crash. I checked on the website for the prime retailer for the engine, but I could not find the back plate, so I am assuming that it is no longer available. I have heard some horror stories about attempts to use compounds such as JB Weld to re-attach the appendage, in which the compound ultimately failed. Has anyone out there any suggestions about where I can find a replacement back plate for this particular engine? Any advice here would be appreciated.

OS stopped making the cast needle valve lug because they broke easily. Its a good thing they usually broke leaving the hole on the backplate intact so you could file and shape the backplate so you could still use the four screws to seal it. They replaced it with a stamped steel bracket and a new needle valve that worked better. I believe you can replace these with the ones from a 46 AX
