Fast Fix Small Engine Treatment, 8 oz | Treats 20 gallons. Helps restore rough-running engines by cleaning carburetors and fuel injectors.

I was having some issues with my self propelled walk behind lawn mower recently. It would fire right up on the first pull, but when I would turn the engine off to empty the bag, it would take forever to restart. It was to the point that it was literally wearing me out to get the engine to turn over again. I always change the oil; clean or replace the spark plug and clean the air filter before the start of every season. I did some research online and found the carburetor could be causing the issue. Rather than remove and clean the carb, I decided to try an additive. I have to say this product exceeded my expectations. I pumped out what fuel was left in the mower and discarded it. I filled a 2 gallon gas container with fresh fuel and added an ounce of the Fast Fix. The engine appears to be running smoother and almost always restarts with one pull after the initial start up. I would recommend giving this a shot as an economical solution.

I have lots garden tools that runs on gas, I follow maintenance guideline and everything works as it should but some are pretty old and runs little rough even after tune up. Figure this treatment might help making some of the rough running equipment run better and it sure did. my edge trimmer alwyas splatters when I 1st started and idles Hunts a bit until it gets hot, after using this treatment, it ran smoother and starts quicker. also added to my mower and it did the same. My chainsaw which I use rarely and always hard to start and after running a while, it will die and hae to wait a while to get it restart, after adding this to it, it amde a big difference in starting and have not stalled out since the treatment. Will be using this prior to winter storage on all my equipment, two or 4 cycles.....

I started using this along with recreation grade gasoline (90 octane, no alcohol) a few years ago. All six of my small engines and a 6 hp outboard start easier and run better. Well worth the money and effort.

Git my Generac Generator running like new after the unleaded gas went bad after a year of sitting.

This STA-BIL Fast Fix treatment is a handy addition to my small-engine maintenance supplies. It’s easy to use and has helped keep my equipment running smoothly, especially on engines that sit for a while between uses. I like that it’s designed to clean the fuel system while helping with overall engine performance. A simple product to keep on hand for routine small-engine maintenance.

Wow... This little WEN Generator has been sitting for 8 years with the same gas in the tank. I drained the tank, put some fresh gas in, and--nothing. Changed the spark plug--nothing. Used starting fluid--nothing. Bought this, added about 1/2 an ounce to a gallon of gas, poured about a quart in the tank, hit it with starter fluid, pulled the starter and WHAM! I let it run for about 15 minutes and shut it off. Next day it hit immediately BUT kept stalling out, then wouldn't start at all. I blew a little starting fluid into the gas tank (not the air cleaner or the carb), gave it a yank, and it started but ran a little rough for 10 minutes and needed to be choked. Gradually, I eased the choke back, let it settle down, and ran for half an hour with no problems before I shut it down. Next day, filled it up with with regular gasoline, it hit and ran the entire day. Without it, the generator was going to the dump. Important to note that this isn't a fuel additive! Use about a quart of gas and shot of it to get your engine running and clean the carb and THEN fill the tank with regular gas and let it work the stuff out of the fuel system. Your engine doesn't want this stuff full-time.

this did seem to help my new lawn mower. It was choking a little on the ethanol and ran better after adding a little of this. I was going to add a little oil but the smoke is a dead give away. This did help and left no visible side effects.

I used it, didn’t see much improvement. I doubt I will get it again. Products like these are usually a better idea than it is in practical application.

Seems to work well and cleans out my small-engine fuel systems.

This is amazing stuff! Saved 2 mowers and a generator. We swear by it!

I don't write a lot of reviews, but it's worth it for this stuff. My snowblower carburetor was pretty clogged, to the point of hardly having any go power. Used one application and a couple uses later, it's now running like new! Def worth it!!

Product work as instructed! I used 2 ounces to 10ltrs to fix idle on 9.9hp Yamaha outboard idle issue! Left the 91 fuel in 8months and it turned to varnish blocking up idle circuits! Made new batch of 10ltrs of 95 fuel and two ounces of Fast Fix and run for 30min and it fixed it perfectly 10/10

Had my snow blower repaired but would not start or even turn over when it got cold. Gummed up carb. Put this in the tank and a week later it started on the first pull. Awesome product. Would of never believed the hype but it actually works great.
