Do not remove the power valves. We are just making the power valve restriction holes smaller. The two holes behind the power valves are really jets. The problem is they are too big. So we make them smaller.
Cold start issues. You will quickly learn how many times you have to pump the carb to get it to start. If the carb is adjusted properly it will be a little bit cold blooded until it warms up.
The mods are easy to do. You can do them yourself. But you will need to have a wide band O2 sensor to get the carb really dialed in.
Are you asking about the emulsion holes?
The advantage of the annular boosters is the carb will work at much lower engine speeds than down leg boosters. Hence the drivability of this carb can be made very good. In other words you can run a bigger carb with annular boosters than carbs with other boosters...
