Rust on carb bolts

Recommended Posts

I have a YZ250F with a standard FCR Keihin carb. Inside the carb below the float the bolts holding body of the carb together are rusted. They are oozing small amount of rust inside the float area. Im wondering if these are something I could replace to get rid of the rust. Im not sure how they could be rusty perhaps the previous owner left the carb sit too long. Just wanted to make sure this wasnt an obvious sign I need a whole new carb or perhaps something I should not touch (since I have not opened a carb beyond this point). I inserted a pic, this isnt my carb but it shows the bolts I am concerned about.

So is the rust an issue I should be looking to swap out the bolts or replace the entire carb? its a used bike so I'm sure someone used pump gas. I use EtOH free and treat the gas.

Do not worry about that corrosion, it is not an issue.
