I'll bet it'll work fine. If it's in good shape, put it on and run it. It's pretty close to start with and if you notice any minor problems, you can correct them down the line, like any carb tuning regimen. You may want to consider putting a small base Rochester 2G on the Merc manifold. The throttle bores are a little larger, but if you put it on backwards, everything lines up, fuel line, throttle linkage, and even the automatic choke. It's basically a better carb to start with and parts and availability are much better.
