Just picked up a Briggs & Stratton 5 horse in excellent condition with a nice chrome pipe. The gentleman was nice enough to include a brand new Briggs Raptor carburetor. He said the carb was not compatible with the standard fuel tank on it. Do I have to find a raptor fuel tank or is there some other trick to making it work with the standard fuel tank? I saw a baffle kit for a raptor tank available at comment is this what I need? Need a little help Merry Christmas
