One product I used extensively when I had a dealership workshop was Merc's Power Tune. Run the engine, at idle on flushers until warm, then increase the throttle while spraying this stuff straight into the carbs. Then, while still spraying, let the engine stall out. Let the power tune sit for 20 to 30 minutes, then fire up the engine. Smoky as billy-o! And watch the run off water. It'll be black with carbon. If you want to de-carbon a piston/combustion chamber or have a few gummed up rings, this stuff is the real deal, but if the problem is a worn engine, or any other damage, nothings coming out of a can will fix that.

spray some water in the carb while it's running. Has to be a warm motor when you do it. That will work as well as Seafoam as a decarbonizer will and water is free.. There are better products that will work as a fuel system cleaner.

Seafoam is a crazy expensive fuel stabilizer, 1 oz. per gallon of gas. Almost three times the price of Stabil [links]

I have used it and it smokes a lot. Does it decarbon and motor? Does it clean the fuel system? [links]

Duration: Until it helps, or you decide it is snake oil. It won't hurt a thing, except maybe your wallet.

Beside above, can I use seafoam as a carb cleaner? Use Sea Foam Spray to safely and effectively clean residues and deposits from intake valves, chambers and compression rings! Sea Foam Spray delivers a high concentration of petroleum cleaning solvency and lubricity to carburetor throttle valves, intake runners and valves, and chamber areas.

For Carburetor Intakes Run engine to warm intake, then shut off. Remove air filter to access carburetor throat. With air filter removed, start engine and place tube nozzle into carburetor throat. Depending on engine size, use 2 to 4 ounces sprayed in bursts to avoid engine stalling. [links]

Can you clean a carburetor with wd40?

[jessw1]

Insert the open end of the hose section into the Sea Foam and fuel mixture. After running, shut off the engine and reconnect your main fuel line – all done! Pour the remaining can mixture in the tank or use for other engines. 1 pint of Sea Foam mixed with 2 pints of fuel will treat several outboards.

Now the Pontiac has 105k miles. Thinking I might try it again this weekend to see how much smoke I get here

[bitcoindonor]

I wouldnt bother on anything with under 100,000 miles on it though you probably wont need it. [links]

[morize]

I still think all are snake oil but i do buy them from time to time when they are on sale. Lucas mainly for the buy one get one free bottles. here

[Ewald]

Its not snake oil and really does work.

[X0nic]

The stuff is out there. Plenty of it but who knows really what works on what. Not many independent places/people have done before and afters. more

Keeping this in view, how much seafoam do I need for a 2 stroke outboard? here

[Alex]

Can you add too much seafoam to gas? [links]

[ralphmcclure]

Similarly, can you use seafoam in outboard motor? Safe & easy to use in all 2- & 4-stroke gasoline marine engines, inboard & outboard. Also great for all types of personal watercraft (PWC). When added to marine engine fuel, Marine PRO works to clean & lubricate your entire fuel system. here

1 pint of Sea Foam mixed with 2 pints of fuel will treat several outboards.

[knascit12]

For cleaning, use 2 or more ounces per gallon – the more you add to fuel, the better it cleans! For 2-stroke pre-mix, add 2 ounces per gallon. When stabilizing fuel for storage, use 1 (one) ounce per gallon of fuel. Sea Foam works to stabilize stored fuel up to 2 years. more
