emission controls
my 84 f250 has two, 3port port vacuum switches i believe they dont work. i have no vac going to the emissions switches on the valve covers.the anti stall dashpot on the carb dont work and the choke has no vac at its hot air tube. the first vacuum switch has vac on the red line.
how does the choke hot air tube work along with the electric part?
how can i test the switches?
