I want to make a simple go-kart with a gasoline engine. I have a 3.5 HP Briggs & Stratton motor from an old power washer. We don't want a high speed racer, just a fun vehicle for goofing around. Least amount of $ out of pocket is a big priority. I am making this for my teenage grandson, so it must be adult-sized. I am a jack of all trades handyman, but DO NOT have access to welding equipment . This could be made out of 2X4s, plywood, metal pipe, whatever. I also need some advice on gearing or direct drive w/ some sort of clutch arrangement. I don't have any experience in this particular area, so any advice is greatly appreciated. Thnx.
