I recently bought a 16ft Forester with 1985 Mercury 90. I took it out several times and it seems to run O.K. Bought a Clymer manual to familiarize myself with the engine components and do the winterizing. One thing that I noticed, is that there seems to be a rather small slot (1/4"by 5") on the top rear of the engine shroud. This appears to be the only place that allows air into the the carburator area. There is a sheet metal plate held on with two screws which if removed would increase the opening signifcantly. Why is there about 1 sq. in. of air vent(on the downwind,somewhat vacumized side of the engine) feeding approx. 4 sq. in. of wide open carb? Does this seem adequate or should the plate be removed?
