Hi Bill, depending on the quality and degree of restoration you are doing on the car, I’d not get too carried away with external cleaning of the carb.

Unless the restoration goal is to look absolutely NEW, a bit of age darkening of the carburetor is perfectly acceptable.

The area that needs to be clean is the inside of the carb. Buy the stromberg jet tool if you haven’t already, Remove all the jets, emulsion tubes, needle screws etc. Clean these items in a carb cleaner solution. Then inspect each part with a magnifying glass. Often there will be residual varnish, dried gasoline deposits on the brass jets. It is important that all residual dirt is removed. I often use a piece of ‘tag wire’, from a price tag or identication tag, this wire is small, and seems to work well to gently scrape the residue off. The accelerator pump check valve is also a power valve, so it must be clean and seal correctly.

Make sure the brass tube that goes from the main jets up to the inside of the venturi is clean. And make sure the small air-correction hole in the top of the venturi support is open into the brass fuel tube If this air-correction jet is not open, that throat of the carb will run VERY rich, flooding it’s cylinders.

Hope this helps.
