hey bout to install the old carb today few quick questions..... first im in ky so no emissions to worry about but im not doing a complete removal just yet cause im unsure on a few things. first since im replacingthe intake and the carb where can i mount the vacum advance lines? (weber 45 dcoe by hte way) also since there isnt a return on these should i just cap my old return for now?(ill pull it eventually) can i leave the emissions on and just pull and cap the hoses im not using?
