Why oh why would you post two threads with the exact same problem, 20 minutes apart? It will become very confusing for everyone. Please delete one of them. After that post the engine model, type and code numbers, plus include the part number you used to rebuild the carb. How long has this been going on? Did it start slowing over time or just at the beginning of this season after being stored with fuel in it?

I have one. It surges when first started, but that stops when I put a load on it. If it tills well, don't worry about it.
