Small Engines (Lawn Mowers, etc.): GX 620 Carb

Question
I have a GX 620 motor on my generator. It will not run or start. It does run when I spray starter fluid into the intake. I have removed and cleaned the carb and still have the same issue. Your thoughts

Answer
Have you made sure the intake insulator and associated gaskets between the carb and the engine are not leaking?  If the gaskets are sealing and the insulator is not warped then the problem must still be in the carb.

Did you use air from an air compressor to blow through all the carb holes?  Did you spray carb cleaner through all the carb holes to make sure the passages are open?  You can usually see the carb clean squirt out of the carb passages...wear safety glasses!  

FYI, I have had to clean some carbs a few times before I got them to work.

Let me if you find an intake/air leak.
