I can't seem to get this electronic choke adjustrd properly....it would appear that the metallic spring is installed backward on the unit.I have the wires connected correctly....the red wire connects from a always on 12v source to the black box of the electronic unit....the white wire connects from a ign. keyed 12v to the black box.....2 black wires come from the black box and connect to the choke unit on the carb...they have female and male connectors so as not to get them mixed....the keyed source allows power to the metallic spring which turns counterclockwise as it heats....Now to my question.....this spring has a hook on the end of it......the carb choke boss that this would POSSIBLY hook underneath to, raises upward as the choke module is turned counterclockwise and the choke closes....then the spring heats up and rotates counterclockewise gradually returning the choke boss and therefore the choke plates to open....if this is correct I have taken my coiled spring off
and reversed it to make this thing work this way....I do not think this is right....what for then the heat sensor attached to block....I have all the literature on this unit....one of my biggest guestions is does the spring hook go under or over the choke boss as it will not INSERT TO or ATTACH TO as the directions call for...thanks for help....this has been along on going problem for me.....it does not work right no matter how many adj I make...brian 455 77 ele with orig mh carb
