I have a 1992 4.3 2 barrel carb and i dont belive that the choke works correctly.....i have to manualy open the flap in the center (the thing that block the barrels of and opens them for air) to maintain an idel. My choke is getting around 10.45 volts + to the chock wire and i am not sure how much tension to put on the coil in the choke house assembly. Can someone help me out?
