hey thanks I was looking everywhere for that info. The L-6945 which is a 4150 main body I know I can use so it's not t total loss. I did some reading on the 4180 models. They are just modified 4160's. So in theory can I convert this 4180 to a 4150, using the same kit to do a 4160 to a 4150? I know I'll have to use the primary block that came with it. I have a few old 4150's I can salvage parts from. They'll probably bolt up. The only thing I'd see being a problem is that the 4180's had their idle mix set at the factory and it cant be adjusted. Would there be any benefit to running the annular boosters? As opposed to just a plain old 650/4150
