STA-BIL Fast Fix - Small Engine Treatment, Cleans Carburetors & Injectors, Fixes Rough Running Engines, Eliminates Water, Carb Cleaner & Fuel Injector Cleaner Treats Up to 10 Gallons, 4oz

I will say I have always said products like this are a scam. I have tried a couple different products and could never really tell a difference in performance, idling, starting etc. I've been fighting with a 2-stroke outboard for a few weekends. I rebuilt carbs with new OEM carburetor kits. And I went back into them twice and could find nothing dirty or wrong. I cleaned passages with carb cleaning tools, not just spray or air pressure. I did all I could and still had rough idle and intermittent stalling.I had heard about this sta-bil product and thought for the price I'd try. I mixed accordingly and went and ran the boat around the lake for about 15 minutes. Got home, put it away and didn't think about it until the next weekend. Took it out the following Saturday, again, not really thinking about it. After idling out of the canal and then back in it dawned on me, no stalling, no lean sneeze, just a perfect idling engine. I don't know how I couldn't have got those carbs clean, and I don't know what this stuff is that got what I somehow missed, but I'm sold on this green magical mechanic in a can.I then told a neighbor about it who had just purchased a used boat with a motor that had not run in many months. It started and ran but not well. He bought some and mixed accordingly and his motor, after a few days, runs smooth as can be without him having to go into the carbs at all. That sold me again.Side note, I only run non-eth in my 2 stroke motors so can't comment on its fight against ethanol problems.

Amazing results: 10 yr old weed string trimmer was hard to start every year and would stall out when switched to full- throttle. I added just a small amount to the tank (also small) and not only did it start immediately, but the engine ran strong and at a high RPM like it was new again. Since these run off a gas/oil mix, I was expecting the carb to be getting too gummed up but, I really think this will clean it out considering how well it ran after just one application. I plan to start using this on my mower and generator next!

Put in a few of my lawn equipment, it seems like it worked and they are running better no more rolling when at low idle.

I have a 20 year old self propelled mower with a four stroke engine. The engine started surging badly. After changing the plug , getting fresh fuel and checking the air filter it still surged.I learned that this problem is usually caused by clogged carburetor gets. After putting two cap fills of the product in the mower tank and running the tank dry , the mower returned to full running condition. Quieter, more power and easier starts. I plan to use it on a two stroke weed wacker next.I highly recommend the product and am most pleased with the outcome it produced.

I let My mower said all winter with the gas in it which I'm pretty sure went bad so I couldn't get it started this summer.I Bought this and added it to fresh gas and the motor started up after the third try. It smoked a little for about the first 10 minutes but it's worked ever since then.If you're having issues with him or after storing it I would highly recommend trying this product. You might have to clean the carburetor as well but this stuff helps.

My lawn tractor was running rough first thing out of the shed this spring. I removed and disassembled my carburetor and used some carburetor cleaner, but it was still hunting. I added this to a fresh tank of gas and ran it for a few minutes one night to get it into the carburetor. The next morning, I started the tractor up and it was running like a champ! It's my new go to!

Used on my gas weedWacker and lawnmower made it more quite don’t know how long it will last but it’s good product accidently mixed oil n gas into lawnmower and used this to clean system. I first removed oil n gas liquid then used this with gas to clean ran for 10 mins.

Noticed a small improvement in engine performance with the first use. Hopefully use of the produce over time will lead to increased engine performance.
