Idles rough in gear

check your timing and also has your distributor been recurved?

where is your vacuum advance hose for the distributor hooked up to the carb at ...are you using the ported vacuum port on the carb?

since you have an electric coke...check the fast idel speed on the electric choke..and make sure once it is hot that the fast idle cam releases....and them check your idle speed....

just somethings to check..
