Works As intended.

The best stuff on the market to getting a four stroke engine back up and running for the season. I highly recommend it. It is getting a little expensive but it’s kinda like a carburetor cleaner and a tuneup all in one

Great product! Fired up the engine on the first try. Snowblower didn’t start due to gasoline I had left in it from prior winter. This product worked great! It’s alive again!

Why did you pick this product vs others?:ggggggggood price

I had to treat my lawn mower four times but now it starts right up and runs/sounds new. On the 1st treatment I treated the gas tank and the carburetor and had no luck. I tried something not listed on the can, I unscrewed the spark plug, sprayed some product in the spark plug chamber and on the spark plug gap. Screwed the spark plug in and it started up. I mowed the yard. On the 2nd treatment I treated the gas tank and the sparkplug/sparkplug chamber and it started right up. I mowed the yard. On the 3rd and 4th treatment I treated only the sparkplug/sparkplug chamber and it started right up and I mowed the yard both times. I have mowed twice since then and have not had to use the product either time and after four treatments the can still has some product left in it too. I'm pretty sure the problem was the ethanol in the gas causing the startup issue with my mower. Probably gunked it up good and this product un-gunked it. Only buying ethanol free gas for the mower from now on.

I have a 20+ year old John Deere push behind lawn mower. I have had a lot of problems starting my mower even after it came back from being serviced this mowing season. So, I thought I'd give this product a try after reading the reviews for STA-BIL. Well, the product was delivered almost a week early (Thanks Amazon!!), so I went right out to see if it helped to start my mower. I unscrewed the air filter cover and gave the carburetor intake a fast squirt with STA-BIL. Then re-attracted the air filter cover and pulled the cord...nothing...I pulled the cord a 2nd time and the mower started right up!!! I have mowed my lawn twice since then and with a little squirt with STA-BIL it starts on the 2nd pull every time!! No need for a new mower...I couldn't be happier!!

Product works well in getting my 15 year old old mower to start, but at only 2 oz it’s very expensive and I feel I will need a new spray can once or twice every season. Also the squirt nozzle pointing vertically at the top of the can is not ideal as you tend to get the material on your fingertip trying to squirt it into the air filter/ carburetor or spark plug hole.

Helped to start generator, snow blower, and any gas engine item I have. Always keep s couple cans on hand. Works great!
