Re: heater/vent vacuum tube routing

Having the hose missing might also explain any roughness or missing of the engine at idle - vacuum leak at the carb base. Assuming that is the case. I would still check the line that "powers" the vacuum actuator for the defrost door for being in poor condition. It's something that you will probably only have to fix one last time if you use silicone tubing.
