I'm overhauling a Mistral and it turns out the volcano orifice is pretty severely nicked. The HP seat looks brand new so I'm sure it's the orifice causing the leak (The guy who sold it to me off the back of the truck told me it worked fine. )
I used steel wool, pencil eraser, etc... but no joy. Is it worth trying to grind / resurface the volcano orifice with a dremel or will it widen the orifice too much so the HP seat will not seal properly? In all the Mistrals I've rebuilt I guess I've been lucky, the volcano orifice has always cleaned up nicely.
Your collective sage advice is welcome.
