  If your Mercedes-Benz Water Pump engine lacks power, consider the following: * The air cleaner might be clogged; clean the air cleaner. * The muffler might be clogged; clean carbon from the muffler. * The exhaust ports might be clogged; remove the muffler, rotate the engine until the piston is at the bottom of the cylinder, and carefully remove all carbon from the exhaust ports with a wooden scraper or blunt tool. Blow away any loose carbon with compressed air. Briefly start the engine to remove all carbon, then reinstall the muffler and gasket. * There might be a blocked filter inline or inside the carburetor; change the inline filter or dismantle the carburetor and clean the screen.
