Helps restore rough-running engines by cleaning carburetors and fuel injectors.: Tools & Home Improvement - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Saved my back from repeated cord pulls. - 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. Review: It made all my aged gas yeard equipment run better - 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..... ## Features - Fixes rough running and hard-to-start engines: Breaks down gum and varnish that cause rough running, hard starts, sputtering, and no-start issues in small engines, helping restore performance quickly - Cleans carburetors and fuel system: Works through the fuel system to clean carburetors, fuel injectors, and internal components, functioning as a small engine carb cleaner without requiring disassembly - Removes water and combats ethanol fuel effects: Helps eliminate water in the fuel system and combats the effects of ethanol-blended fuels, including E15, which can contribute to rough running, stalling, and starting issues - Designed for lawn mowers and small engine equipment: Ideal for use in lawn mowers, trimmers, chainsaws, snow blowers, generators, and other 2-cycle and 4-cycle engines - Easy-to-use fuel treatment: Add to fresh gas and run the engine to circulate through the system, treating up to 10 gallons and helping restore smooth operation in small engines affected by fuel-related issues ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NEG3JHS | | Best Sellers Rank | #10,203 in Automotive ( See Top 100 in Automotive ) #23 in Fuel Additives | | Brand | STA-BIL | | Brand Name | STA-BIL | | Cleaning Agent Formulation | Solvent | | Customer Reviews | 4.6 out of 5 stars 6,933 Reviews | | Global Trade Identification Number | 00073905223034 | | Included Components | STA-BIL Fast Fix - 4oz (22303) | | Item Form | Liquid | | Item Type Name | STA-BIL Fast Fix Small Engine Treatment - Cleans Carbs And Injectors - Fixes Rough Running Engines - Eliminates Water - Treats 10 Gallons, 4 fl. oz.

Although this product is designed more specifically for reactive and immediate use (e.g. while starting the engine after storage, having performance issues, or rough/no starts). However, it can certainly be used with STA-BIL Brand at the same time -during use or storage. Hope this helps. Please feel free to contact us at producttechsupport@goldeagle.com. Thanks for the question! **Q: do you pour it unmixed into the small engine?** A: Need to clear up the directions for this product. You say 1oz per 2.5 gallons or gas then show pouring directly into gas tank on a mower. Obviously no mower tank is 2.5 gallons so people automatically revert to thinking to mix it into their red 2.5 gallon gas container. I realize you can do this too but y’all really need to clarify this. Like “1oz into mower tank is good for 2.5 gallons of run time” something like that **Q: when will the stock come??** A: Asap **Q: Do I pore it in the gas tank on my rovan Baja gas rc or mix it with gas just asking** A: Either would work but I just poured it in the tank and it worked well ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved my back from repeated cord pulls. *by B***L on June 12, 2026* I was having some issues with my self propelled walk behind lawn mower recently.

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. ## Frequently Bought Together - 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 - Gumout 800002231 Carb and Choke Cleaner Jet Spray - 14 oz. - STA-BIL Starting Fluid - Prolongs Starter Life - Upper Cylinder Lube - for Gasoline and Diesel Engines - Guaranteed Faster Starts Down to -65°F, 11 oz (22004) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/163977858-sta-bil-fast-fix-small-engine-treatment-4-oz](https://www.desertcart.at/products/163977858-sta-bil-fast-fix-small-engine-treatment-4-oz) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-27*
