STA-BIL Fast Fix - Small Engine Treatment, Cleans Carburetors and Injectors, Fixes Rough Running Engines, Eliminates Water, Treats Up to 20 Gallons, 8oz (22304), Green

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

Mower was having trouble re-starting after a stop, and then eventually wouldn't start at all. I didn't want to completely pull apart the carburetor to clean it so I gave this product a try and it worked like a charm. I just poured a small amount into my mostly full gas tank, let it sit for a few minutes and did some soft pulls to circulate the cleaner thru the fuel system - and it eventually started right up. The cleaning performance seems to be very good because I've been having these issues for a while which makes routine mowing a pain but now the mower starts right up every pull and runs strong with no stalling. Will be using it in my weed trimmer as well to keep the fuel system gunk free. The bottle size is perfect since it treats 20 gallons of fuel and you only need to use it periodically for maintenance. Great value for the money.

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

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.....
