Loss of power at half throttle and higher. Has random misses causing engine to shudder. Sounds like there may be a knock inside. Top plug fouls.<br />Have read other problems and see mention of "stator". Not familiar with this-what is it?<br /> <br />What I've done so far:<br /><br />Replaced sparkplugs. <br />1. Checked spark - Both plugs are firing<br />2. Checked compression - both cylinders are at 115<br />3. Replaced fuel filter between tank and fuel filter on engine. <br />4. Removed and cleaned fuel filter on engine.<br />5. Cleaned carb with carb cleaner. Power increases if we blow air directly into carb but still shudders and misses. No gas leaking from carb.<br />6. Squeezing bulb does not increase power.
