The most important tool is a good quality, sharp phillips head screwdriver. You will need this for most of the project (loosening carb boots, taking apart the throttle housing for slack to pull carbs out, removing tops of carbs for the shims, and most important, getting the screws loose on the float bowls to replace the jets). A small wrench to remove the jets. Its a pretty easy job, take your time and read the directions well. Figure a couple hours.
