Hi new to the site! My Kawasaki FG300 won't run without the choke on. I have cleaned the carb out twice already.I let the carb soak in carb cleaner for most of the day,same problem. I noticed alot of fuel vapor in the carb throat after the engine dies. I know there are some pretty small passeges in that carb, the engine had been sitting for about 10 years. Thanks!!
