Briggs Vanguard to Kohler carb adapter

thingiverse

I built an adapter to install a Kohler Command Keihn carb on my 16hp Briggs Vanguard engine in my golf cart. The single barrel 16hp carb I had, with no accelerator pump, had a very noticeable dead spot when making rapid throttle transitions. Switching to a horizontal shaft 25hp Kohler Command Keihn carb with an accelerator pump fixed this problem completely. This adapter will fit the 2-barrel Vanguard intake from a 20hp or 23hp engine. To do this mod on a 12-18hp Vanguard, I needed to source the 20hp manifold - using a 23hp intake won't work on smaller engines. A picture shows a 20hp manifold; I also have a 23hp one that fits just as well. PLA may not be the best material for this adapter due to its hot operating environment.
