i was on the highway today when all of a sudden my car started running like crap so i pulled over and realized the electric choke was staying closed. after pissing around with it for 10 minutes in the freezing cold i ended up stuffing a piece of kleenex against the "high idle cam?" or that little ear type wieght looking thing behind the choke, so the butterfly would stay open and i could get home. so far i checked the choke wire with a multimter and the key on and theres a solid 12.4 volts there. watched a couple vauge youtube vids on choke pull offs and tested mine by making a mark on it and starting the car to see if it moves a little, seeing that it didnt i removed it and replaced it with another one from another 4 barrel roch. carb i had sitting here. basically the video said it should only move a little when the motor starts but mine has enough vaccum to suck the diaphram right in which pulls the lever to the secondaries all the way. is this normal? also if you know what the other diaphram towards the back does that would probaly help me out also. thanx!
