I have very rust blast that day and engine only has like 10 hours on it but everything is so rust from sitting and a lot of screws and bolts are stripped ,whats best way to remove rust and not sure what this is on the carburetor if it comes out or what but doesn’t look like screws or very stripped I’m using evoporust and letting pieces I can sit to get rust off
. Clean it up with a wire brush Or sandpaper. To get loose stuff off and put ospho on it. It stops the rust
