It's best to invest 12 to 20 dollars in a Chilton's or Haynes repair manual. I prefer Haynes because of the exensive electrical schematics. Also, If you cannot afford a manual....you can reference some at your local library. That is, if it is the stock factory carb.

That means you have a manual choke on your carb and not a vacuum advance choke( black little round thing on the lft side of your carb facing your eng.)..the fuel evaporates from your choke being open that's why you have to pump your gas that would be my guess........
Keihin pvk 36mm with electric choke
there is no choke its got an electric choke on the carb
you need a pull choke cable to use it manually and then set it so when closed you can fit an 1/8" drill bit between the carb body and the choke flap.

Yes , but you also have to change the intake manifold
If 2.8 (6 cylinder) fuel injected -- no choke If carb. should be a round black cap that has spring inside (on passenger side of carb.)
clean the carb
