For what it's worth, I have a Clifford intake on my 261 and mechanic suggested a Ford Motorcraft 2100 2 bbl which I purchased and we used. It has what I think is called a hot air choke which takes heat through a tube from exhaust manifold to choke thermostat. When cold, choke plate is closed, as engine warms heat from exhaust tube opens choke plate to a non choke position. We are not using manifold heat. It was 9 degrees here this am, and she started up on first try. We did not try to mess with linkage, we used cable and firewall mounted gas pedal. Hope this helps.
