In a severely demon possessed engine, I once took it off and put it in a sink of water so I could pressurize the engine by blowing through the fuel line. If you'll block the carb intake and the exhaust, you'll find any air leaks in the engine. In mine, I found that the engine was sucking air through front bearing very freely. A new bearing made a major improvement.
