Sea Foam in carbureted engines with rubber gaskets and seals [SOLVED]

I keep seeing Sea Foam advertising referring to injectors. Can it be safely used on old farm tractor engines from the 60’s that have a standard old carb with rubber gaskets, seals, etc…and will it help to clean carb, and intake valves, etc?

Thanks for the question, Alan.

Yes, Sea Foam can be used safely on old engines. It’s made with 100% safe petroleum cleaning and lubricating ingredients and does not contain any harsh chemicals, so it’s safe for rubber gaskets and seals.

As far as cleaning, yes! Sea Foam cleans anything the fuel comes into contact with. Works great to clean carbureted engines.

For cleaning, the best way to use it is to add a full can of Sea Foam to a low amount of fuel (2-4 gallons), and then run it until almost empty to allow the Sea Foam time to run through the fuel system and clean.

Sea Foam High Mileage would also be a good choice (it’s made to be very strong, cleaning stubborn deposits and residues in older engines).
