muriatic acid, OK for carb soaking?

I used muriatic for cleaning steel once. Never again. Just having the jug in my garage caused all kinds of corrosion and issues on other tools and metal parts stored in the garage. It was a disaster.

Any plating on steel parts will be stripped by muriatic. It can etch aluminum and will completely dissolve zinc, which is found both in cast aluminum alloys and in brass.

It can probably work, but is not how I'd go about cleaning carburetors unless I was planning to completely restore with new platings and finishes on all parts. Caswell offers tons of finishing kits for that sorry of tune and I'd ask them the best way to go about cleaning and refinishing if that was the goal.
