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

Works Great, at first didn't believe all the reviews, I've bought 5 chainsaws from one season to the next. After each winter couldn't get them to start. Followed the instructions to flush and let sit for a few days. Every one started and ran great. Hands down, this is a remarkable product for cleaning out blocked fuel systems from sitting all winter would recommend it for all 2 cycle engines and use the stable blend for winter as well as anytime use to prevent fuel spoilage.

10/10 Excellent product, really helped me with my snapper snowblower that kept stalling over and over during a blizzard....I highly recommend this product. This is not a paid promotion. Thank you STABIL FAST FIX

This stuff is amazing. It revived my old leaf blower and saved me several hundred dollars. Now I’m putting it in other 2 stroke engines and they are all coming back. Take your time. I let it sit, and it ate away all the varnish inside the carb. Really great product. I’ll definitely buy again.

This stuff is flat out amazing for 2 cycle small engines, works like advertised. 4 cycle isn't as good, if your engine hasn't ran in years, you'll still have to clean the carb, but it does help some. The 2 cycle oil for one is a lubricant and inhibits varnish buildup (especially a synthetic premium brand), and usually premium oil has a fuel stabilizer in it. Plus if you don't have a float bowl, there's not enough fuel for phase separation. I also use it in my mix for my ultrasonic cleaner when cleaning carbs. Overall a very good product, but understand it's limitations in this modern age of ethanal fuel.

This stuff actually works put in proper amount with fresh gas and watch your small engine run smoother and more powerful than ever. Very surprised.

I never write reviews, but I am this time. I have a snowmobile that I haven’t started in 2 years. I tried starting it and it would crank over, but wouldn’t start. So, I changed the spark plugs and drained the gas. I put in new gas/spark plugs and it still wouldn’t start. I put in about 3 ounces of Fast Fix in 4 gallons of gas. Cranked it over a few times per the bottle directions and left everything sit for about 48 hours. Turned the key, and it cranked a few times and fired right up….i was totally shocked!! Definitely worth the money!

This product is amazing. We tried so many things. Had the mower in the garage for cleaning the tank. We planned to replace the gas tank as a last resort. Before the mechanic got around to working on removing the tank, we tried this product, and it worked. My husband is so happy. It made his day. The lawn mower worked well and did not cut off at all. It is so great.

I haven’t tested the product yet. But it arrived without a cap on it. Thankfully, the seal at the top was not punctured.

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

Worked perfectly.

Great product. Snowblower was struggling to start then popping when running. Put in and ran for 15, then let stand for a few hours and started again. Completely running smooth. First video was loud running and popping noise. Not smooth. Then this is after use.

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!!

I was weary at first, but I added a small amount to each of my snowblower, lawn mower, and gas trimmer, and I can hear a subtle difference in the smoothness of the engine's run, especially my lawn mower. I maintain my seasonal tools with gas treatment and oil changes, so this is just an add-on, but I bought a second bottle because of how pleased I was.
