Use of Sea-Foam in Older Engine

[Bulbash]

Guys, I'm planning to run some seafoam through my 1989 Ford 2.3 engine... I used it in my cars, snowblowers and lawn movers with great results. Now, my boat has much higher value to me than a snowblower and knowing that engine is so old I wonder am I safe to ad it directly to the carb and / or into the spark plugs to remove carbon deposits...

If you need to knock carbon deposits loose there are much better products specifically made for the task.

Such as?

Just trying to solve a runon / diseling issue..

I don't know about better products, but I would add it to the fuel tank. It will help clean the whole system and remove carbon from the combustion chamber slowly, which is better than dumping it down the carb. Just my opinion.

Howdy,

"Decarbonizing" is more a carbureted 2-stroke "thing" and not really effective in 4 stroke engines since the kind of carbon (from burning oil in the combustion chamber) doesn't occur in 4-strokes at the same level (unless you run the engine continuously with the choke ON!) or you have NO rings........ Then you have MUCH bigger problems.....

Snake oils are usually usually not very effective in reducing runon or "dieseling' in a 4 stroke either.



You might have a look at the following Mercury Service bulletin.
