Why do I have to change my oil so often?

Oil is made of molecules different chemicals that provide a barrier between the metal parts. As oil is used it is contaminated with metal particles, carbon, and fuel.

How do I connect my throttle cable to my Briggs carburetor?

This applies to both the Animal and World Formula engines. The throttle cable should have a small ball or small cylinder on one end, this is the end that should go into the carb. Take the slide out of the carb and locate the slot on one side, the throttle cable goes through this slot and the ball or cylinder hooks into the cutout on the bottom of the slide. Be careful not knock off the clip inside the slide that holds the needle.
