Hi, I have a RBS carburetor 1 barrel in my 1974 Ford maverick 250ci 6L, but I have a question, My Choke rbs carter is not working in this moment because i dont know where i may connect it because my carburetor doesnt have a electrick choke, i supouse that this choke wor with heat air or haet water, plese anybody know where the RBS carburetor without electrical choke must be install or work, if with heat air or water air??????? thanks
