I have a 86 Mercruiser 120 and the numbers I got off the carb are 1389-8490. I can not find which kit I need. Even better is I don't know if this is a Rochester or a Merc carb for sure as I have been told two different things. There is one screw adjustment.
I went to Napa and they have three different kits to choose from. 1 kit for a Rochester, and 2 for a Merc. carb. The difference in the merc carb kits were one had a 90* elbow in the kit and the other had a straight piece. Forgot the technical name for it.
Thanks.
