A simple look at a simple Briggs & Stratton carburetor from a 2016 Murray Lawn Mower. How to pop the white plastic valve ports out to clean. This is very easy and quick. This is going to be the case for most mowers left with ethonal over the winter months without use. Use non-ethanol fuel if you intend to leave the mower more than a month. Or test out some additives if you like. Test it. Place a mason jar of ethanol e10 or e15 on a shelf for a month. Did it separate?
The mower started first pull like it should.
You got this.
