Cleans Out Working Carburetors
Size: 2 fl oz
I recommend this product for engines that will in fact start but not run well. I highly recommend it for that specific purpose, which it is designed for. It cleans the inner workings of the carburetor. Of course, you will have a cleaner carburetor if you take it apart and clean it with proper tools and a proper carburetor cleaner. You spray it in the gas tank, start the engine, and let it run a bit. It will not start an engine with a totally plugged up carburetor. Nothing is going to do that. Nor is it a fuel stabilizer, as one previous reviewer seemed to think. Nor is it a product to be used to bring life back to stale gasoline, as another reviewer seemed to think. The only thing to do with stale gasoline is drain it out and pitch it. Nor is it a product to be used for cleaning a carburetor you have taken apart to clean. You should use a proper carburetor cleaner for that purpose. I've given it four stars because it cleans out mildly plugged up carbs. It is not a miracle solution for really neglected carbs as the name suggests.

It works like magic, saved me $150.
Size: 2 fl oz
I filled 1/4 tank of gas into my snowblower which I could not started, sprayed about 15 seconds of Start Your Engines, rock snowblower to mix well, let it sat for an hour. I pulled string and yet couldn't start engine. Unscrewed spark plug and spray some into cylinder, put the spark plug back and pull the string. ENGINE STARTED!!! SAVED ME AT THE LEAST $150.
