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.

Flimsy Nozzle
Size: 2 fl oz
The nozzle is so flimsy at the moment I pressed on it it popped off the can into the gas tank. I didn’t press it softly but I also didn’t press it very hard either, getting it out was a huge pain in the butt.
