Sea Foam works, and it works well is the jist of my review. I tried this on my five year old Ariens 926LE snowblower with 9.25hp Tecumseh that was getting the oh so common idle surges, not wanting to idle right, and popping at full throttle. We all know what that means. The carb jets, bowl is starting to plug up with varnish and gunk. Now at this stage you either find a way to fix it yourself or drop it off at the small engine shop for a $99 cleaning/rebuild.
So I tried Sea Foam after reading reviews all over the internet. One ounce in the one gallon tank just as the bottle says. Plowed snow for an hour, and when done dropped it to idle to clean it off. Instead of sputtering and surging like it had been, it idled like a champ. Smooth as the day it was new.
My neighbor had his blower out too, and I asked him if he wanted to try an ounce in his tank. I added it and when he was done, his low idle was almost as good as mine (his blower is much older, may take a few more tanks). It worked on his machine too, same way it did mine. It cleaned the carb out.
WHAT IT'S MADE OF: I decided to look up more info on this Sea Foam and see what was in it. A combination of Pale Oil(similar to diesel), Naphtha and Isopropyl Alcohol in the right amounts. You can take this info right off their MSDS sheet. They make no secret of it.
You could make it yourself at home and try to figure out the ratios, but since it's very cheap per can, why bother? It just works. That's why it's been bought by consumers for 70+ years non stop. Whomever found just the right mixture way back then was a lucky guy. You see motor cleaner stuff come and go from everyone else, but Sea Foam just seems to stick around at all the shops and stores. There is obviously a reason for that and now I know why.
Buy it, use it in the right amounts and you can't go wrong. Cleans bowls, jets, injectors, lines, etc. just as it should.
It's not snake oil, it's not a secret ingredient, it's just a formula of common chemicals in the right amounts that works like a charm on internal combustion engines.
I'm sold on Sea Foam and so is my neighbor.
