"My Polaris ATV gets through each winter with a slight chance of running clean in the spring.  I have tried other stabilizers and even conceded that I might have to yank the carburetor once a year.  This winter, I needed to plow snow and the ATV would start, but would not rev beyond 2K rpm without cutting out.  Since it would at least start, I tried MIAB.  Followed the instructions and 4 hours later, the engine was idling as smooth as when it was new and it revs all the way up with no hesitation.  Not having to yank thecarb or pay someoneto do it is a great relief.  This stuff works as is described."
