Do you have the one with or without the electric choke? The reason I ask is because the model without the electric choke is jetted richer than the one with an electric choke. All Eddy carbs are a little rich out of the box. You should get yourself a tuning kit with jets and metering rods for your model carburetor. It is very easy to change metering rods and jets. You can these kits from Summit for around $40.00. You can use your carb manual to know which ones to use.
