I don't know a thing about SeaFoam, but I suspect carb cleaner will be far superior as it is actually intended for this purpose. SeaFoam seems a lot like snake oil...

 

From the MSDS I gathered it is a mixture of Kerosene and gun oil basically. Kerosene is however, a very effective carbon solvent.

 

99% of stuff like that is. I used to run lucas in my VW, and to an extent it helps keep carbon off the injectors. But tbh a good decarb every so often works better.

IMO quick fixes often cause more problems later on, radiator stop leak is one that comes to mind...

 

So is the general concensus to try Sea Foam before anything else?

 

If SeaFoam really is kerosene based, it will be pretty good at removing carbon.

BUT carburetor cleaner is specifically designed to dissolve carbon while being fairly safe to the rest of the engine. So carburetor cleaner should be what you use.
