Sea Foam Spray for a carburetor – how it works [SOLVED}

Why would I use Sea Foam Spray for a carburetor if I am using Sea Foam in the gas tank ?

Thank you,

Thanks for the question, Charlie.  The only way to clean a carburetor using any Sea Foam treatment would be by adding to fuel, allowing the cleaning mixture to work through the internal carburetor circuits to clean gum and varnish residues from needles/seats, jets, float bowls, and nozzles. Sea Foam Spray is applied into the carburetor throat, which is where the intake air mixes with gasoline before going over the intake valves and into the combustion chamber. You would want to use Sea Foam Spray to deliver a high cleaning boost to intake valves, pistons, and chamber areas – note that it's straight Sea Foam going into the upper engine, so very concentrated! Hope this helps!
