Hello, I have a 2007 Mercury 5.0 220hp V8. While shopping for the engine manual on the merc website I found manual #31 which covers that engine from year 2001 to the present. It also said it covers MPI as well as carbureted engines. I found a nice link here for downloadable merc manuals and I took a look at #31. Its a great manual, however there is no section on carburetors . Is there an update or a supplement I'm missing? Thanks.
