Hey, I could use some help. After finally deciding the smoke and low idle problem on our motor was a leak in the exhaust system, my husband tried to get the old gasket off and couldn't figure out how to disconnect the linkage for the throttle and the shifter. He has performed a temporary fix with some gasket sealer that came in a tube. We will have to fix this over the winter, though. Any help we can get would be greatly appreciated. The year on the motor is a 75<br />Thanks, joeyp
