I must be lucky,.......I exchanged the carb for a new (reman/old) one. This one didn't load up though. Good! It would also idle, a little rough, but better than before. I started adjusting the idle mixture and I soon found out that I could turn both screws all the way in (idling at around 600) and the engine didn't even stumble.....................What the h***????? Metering rods incorrect? probably. I have sworn off cheapo depot parts. I can envision some carb rebuilder picking mismatched parts out of several bins and churning out carbs assembly line style. Every time I have tried to save a few bucks and get the cheapie stuff, I regret it in one way or the other. You would think I would learn. I think it is time to buck up and buy a new one. Or maybe I will try to rebuild one of these old cores I have sitting around, I could do that for peanuts.....................................
