I’ve been working on a performance lawn mower since i was in middle school…ok, its been sitting in my backyard since middleschool anyways…but i DID DO an engine swap…went from an oil guzzling Briggs-Stratton 16hp to a Briggs Stratton 18hp, and I put really small wheels in front, painted it back…plan on doing straight pipes out the back of it…whenever i get back into it…
