I think seafoam is over rated. I know that will earn me some hate mail but I've tried it several times and while the marketing gets me pumped up, I've never seen any benefit from the product. I bought a bottle, again, and ran a concentrated mix of gas and seafoam, allowing it to soak, then running it under load, no load, etc.  Repeated several times and no improvement. 
I think that the use of snake oil is often overrated.  While a strong solvent might dissolve the junk in a carb, often the best way is to disassemble and do a proper cleaning.  Even if the junk is freed, did all of it pass into the engine, or is some still in there waiting to clog things again?
