Phenomenally. I have a really old lawnmower that was running rough last year, it's rusted up in random places and I didn't want to take apart the carb because it would probably create a chain reaction of other broken parts. I poured 2oz of this in the tank with some fresh gas, let it sit in there for a few hours, and it started up after a few pulls. After that, the lawnmower has been working normally again.

Contrary to the other reply to your question, this did not actually do anything to my tiller which would not start until I physically had to take the carb apart and clear out the clog (carb itself was squeaky clean, just that the hole was clogged by I do not know what).
So, looks like 1 good, 1 bad (or more like indifferent) review for you to consider. I am sure this will make it easy for you to choose. Wink

Anecdotal but it worked for me on a few small engines. It's not something I'd be using all the time but if I get to the point where I'm on the verge of a major service or replacing equipment, why not?

I had a log splitter that regardless of how I winterized it, I always had to spend a few hours every summer getting the engine running again. This product was one of those I'd use to resurrect it.

In for one. My weed whip starts a bit rough and has a few carb issues. Reviews are great on Amazon.

And today I added to my vocabulary yet another name for a string trimmer! Smilie

Nice, I've never heard that one.

Products like this never/rarely work for engines that wont run at all, even when advertised as so. The product needs to run through the carb Jets and if the motor isnt running then the old fuel in the carb bowl and other clogs in the carb cannot be cleared. It can certainly work on poorly running engines due to slighlty gummed up carb jets and mechanical parts as some report.

I have look into how to maintain your small engine like your lawn mower and here is what I found:

1. Drain the fuel for winter. I got a hand pump from Harbor Freight. Few dollars.
2. Use ethanol free if you can. Ethanol attract moisture. Theres a website you can find list of stations.
3. Use fresh fuel, not the ones that been sitting for months! It attract fuel.
4. Change oil, spark plug, air filter once a year.

If you got more to add/delete/not ncessary, let me know.

You want to do this before your jet spray get clog. So I prefer doing maintenance.

I find that just by adding Sta-Bil fuel stabilizer to fresh fuel, you do not need to drain the fuel before storage. Just fill up the gas tank before storage to minimize air/moisture.

You also do not have to use ethanol-free gasoline. Your fuel could sit for 18 months and still be fresh.

But, yeah, change oil at least once a year. I change spark plugs and air filter depending on usage. 3 years max for me, sometimes sooner.

I do this on my tractor, push mower, and snow thrower. Starts right up every season.
