1997 Speedster twin 717s water from weep hole in cylinder head

[Utahhillz]

I just completed my first ever rebuild of a rotax 717 engine after ingesting a allen head bolt head that broke of the carb. I repaced everything from case to crank to rotary valve assembly. I had my cylinders bored and honed and new pistons as well. Engine is reinstalled and fires right up. Ny issue is that I have cooling water coming out through a weep hole in the carb side of the cylinder head. (single carb if it matters). Can anyone offer some troubleshooting advice or what I need to do to fix it?
