Briggs V Twin , Niki Carb , Refresh. On this Statesman Riding mower with a Briggs and Stratton V Twin Intek engine , one cylinder is not running well. I took the carburetor off and tore it apart. Inside the nikki carb i found a o ring that was bad and coming apart. It had one passage way in the nikki carburetor plugged off. The nikki carburetor on the Briggs and Stratton engine is a good carburetor when all is right inside. If you clean the nikki carb well and replace the o rings and gaskets in your nikki carb it should run good again. This riding mower , with a twin cylinder briggs engine is now running good again and back to mowing grass again. The twin cylinder briggs and stratton carb, is really good , unless dirt gets in or the ethanol eats up the rubber parts . When storing i run the nikki carb , out of fuel so the ethanol does not harm the inside .
