Hi Noobie! If you have a manual choke, you'll have a choke knob in or under the dash and on the carb, on the passenger side, you'll see a small cable going to the carb. If you have an automatic choke, you'll have no knob inside and a plastic round thing on the passenger side of the carb usually with a small tube running to it from the exhuast manifold (usually rusted off). The manifold tube is what gives the bi-metalic spring ( inside the plastic cover) the heat to expand and turn your choke to open. Hope this helps.
