My 80s vintage Mercruiser 140 has a choke<br />at the top of the carb which looks like its driven electrically. It has a black mechanism<br />on the fore side about the size of half a tennis ball with a push on wire running into the harness.<br />This seems to go to a microswitch in the linkage<br />below. I lost the manual in a house fire so I'm<br />not sure how its supposed to operate.Also<br />the other end of the choke shaft goes to a<br />cam that seems to be hit by a throttle screw at<br />minimum throttle but not at anything above idle.<br />The cam seems to have no real function except<br />adding a liitle friction to the choke, unless<br />this whole arrangement is installed wrong.<br />Thanks in advance
