I have a 77 model evinrude 35 that has a link on the carb from the throttle to choke bellcrank. When advancing the throttle the choke bellcrank doesn't move just seems like there is a lot of slacking this linkage. Is this normal? Engine runs good but doesn't seem to quite open all the way up seems it should run at higher rpm than it does with throttle wide open and in gear and was wondering if this could be the culprit? Thanks
