Folks: I have a 1983 Subaru GL wagon with a 1.8 engine, and it has a Hitachi carburator that has an electrically heated, bi-metalic automatic chokeoperation. Anyway, the thing has been VERY cold natured just recently, and until it runs for several minutes, it goes like a bucking bronc. The Haynes manual book tells me to check for voltage at the electric bi-metalic heater. I did, and it only reads 1 (ONE) volt. Is this supposed to be all it reads??? That wire is supposed to send current to the bi-metalic automatic choke thus heating it up so that it expanded the bi-metalic coil, and opening the choke slowly. Although the book don't tell how many volts it;s supposed to read, there is an illustration in the book, and the electrical multimeter in the pic is reading 6 volts. I also turned the ignition to the "on" position and put my finget to the bi-metalic coil and it dod NOT get hot as it;s supposed to. Is there something like a resistive wire that is limiting the wire to the 1 volt I'm reading, therefore, not giving it enough heat to make it operate the automatic choke??? Thanks a LOT fo rANY help. Chuck
