Weber carb cold stumble

Put a weber carb conversion on my 87 samurai. Problem is it wont idle smooth when cold, also stumbles and stutters when driving it cold. However runs perfect once it warms up. Fuel pump seems to be a little lacking when at idle. Would an electric fuel pump help? Choke closes and seems to work properly.

thats common it happens on mine all the time i have a elec fuel pump so it dont matter trust me
