Point of reference : I removed the choke cable once again from the carb connection..... with no cable I was not able to move the control into a position where the choke closes. it appears to be blocked by control on the left side of the carburetor that stops the action of the choke, if I manually depress the control arm then the ckoke can be positioned to close.....I don't know how this change happeded, truck was starting fine and now this choke issue.... hard for me to explain.....
