I recently pulled the aisin carb and once I pulled it off I noticed there is a coolant hole that used to flow through the carb plates itself. The weber just has a gasket that basically just covers the hole. I tried adding coolant after everything was buttoned up but it ended up leaking past the gasket and into the manifold. I'm almost thinking about welding/sanding it shut. I have the LCE water bypass/heat plugged and all that. Just wondering what others did on here?
