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.

Efird, a great product

Size: 8 Fl Oz (Pack of 1)

Used this in a Troy Built Garden Tiller, the tiller would stall and hard to crank until we use the Sta Bil Fast Fix, tiller now runs great and does not stall.

Worked great, saved me hundreds.

Size: 8 Fl Oz (Pack of 1)

I've had issues with the carburetor on my 2003 Honda ATV for years. It has needed cleaned regularly to stay running, and one repair shop wanted over $400 to replace the carburetor. One treatment with STA-BIL and it's running smooth again. Very impressive.

Great for 2 cycle, meh for 4 cycle.

Size: 8 Fl Oz (Pack of 1)

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.
