High Compression - Impossible to Start Generac Generator

Описание: My friend Jason sold one of his generators to a contractor. The contractor offered up his old Generac GP7500e to Jason at no cost. No information was provided about its run condition. I assume it has high hours and no longer runs. I turned the engine over and it sounds good, but the compression is really high making it difficult if not impossible to start. It this a parts machine or will it run again?

I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors. Recently I have been using Simple Green PRO HD with good results.
