Seafoam is a marine product, I'd go to a Ships Chandlery (AKA boat shop) and see what they have, I know Castrol sells a similar product. All it is, is a very high detergent very lightweight machine oil. I believe it has some wintergreen oil (Or some other aromatic oil) in it for the cleaning action. Its original purpose was to pickle marine engines for storage. For saltwater boats we used to run the engine til warm, then fogg the intake at idle til the engine stalled. What this did was coat all the 2 stoke internals and kept corosion down. Also cleaned out the power valve area from carbon buildup. You might also find this product at airports where light aircraft fly. It or its kin is used to keep the planes engines from rusting as well.
