One more question regarding the carb rebuild on my 1985 Mariner 150 HP V6:<br />All the gaskets to rebuild the carbs have fit perfect until now. They gasket that fits between the carb and the manifold is the right size and the mounting bolt holes are correct. But the hole over the enricher port doesn't line up. On the carb it is a square hole, and on the gasket it is a round hole that covers over half the port. Is this correct, or should I just enlarge the hole to match?
