In this video, I fabricate a custom intake manifold from angle iron and old bike handlebars. This allows me to use a motorcyclestyle PZ19 slide carburetor which works with a twist grip throttle. It also allows for a remote mounted fuel tank on the top bar as opposed to the engine mounted fuel tank with the diaphragm style carburetor that the engine came with. Engine speed will also be easier to control with this slide carburetor.
