For those of you that have pre 50's Mercurys and wonder why they may not be running up to par in static test situations I have learned that with the lower shoud off there is a tendency for the intake to suck in rich exhaust fumes that form around the engine. This causes all kinds of trouble. Put a fan in front of you engine and your problems are solved. I learned this the hard way after cleaning cards and replacing every electrical componet on the engine. Of course on a moving boat this doesn't happen.
