So i have a newbie question. I was reading about some people that said they would drain the crankcase plug and I was wondering what the benefits of that were? i have had troubles recently with a bad choke cable and running rich and was wondering if i should empty these when I change the choke cables tonight? any info?
Thanks

The plugs are nice to have if you have a stuck float and your carbs fill the crankcase with fuel. They can also assist in draining the crankcase if you submerge the engine in water, or if you pull a cylinder and all your antifreeze goes into the crankcase. If the engine has been running (even rich) there will be little benefit in removing the plugs. I doubt there will be much fluid come out in an engine that has been running.

In normal engine maintenance, removing the plugs isn't required.
