I have a rider with a briggs 14.5OHV. It will run for a little bit then oil pours into the carb from a breather I'm guessing? Is the breather bad or do I have bigger problems.

Make sure you know what a breather is, It's usually a rectangular thing on the side of the engine with a length of hose pointing down. It has a filter element inside. When it's stopped up, oil shows up in the carb. Look at either Home - Briggs & Stratton (http://www.briggsandstratton.com) or Parts & Accessories | Shop & Find Lawn & Garden, Appliance Parts at Sears Parts Direct | SearsPartsDirect.com from Sears (http://www.searspartsdirect.com) for a diagram. You can probably get a breather from your local dealer.

Yes, the breather is bad.
