List,
One of my instructors at school is a Ford Master Certified mechanic
an he knows his stuff. The following is what he told me he did on
carburetor cars (of course they are std center top mounted carbs).
He runs up the RPM and then pours water into carbs, not great buckets
but a fair amount to listen to him describe it. He says it works.
It sounded reasonable, of course you would have to be careful not to
get too much in at once for all the obvious reasons. Not sure I'd
try it the first time w/o someone there who had done it before.
