Hard to start, little power. Black smoke at start. Symptoms indicate flooded carb situation
Suspected problem due to ethanol damage to engine not designed to use it.

Engine now starts easy and has same power as before.
I try to avoid ethanol in my small engines even in those supposedly designed for it. It's a powerful solvent and a potential troublemaker in my experience.

Float needle seat washer failed from old age.
Old float seat swelled up and crumbled, carefully removed all old pieces with a small stiff wire.
After making sure new seat was correctly oriented and centered in hole, I pressed it in with the blunt end of a drill bit that was almost as big as the hole. Then reassembled carb and put it back on the mower.

Question: Needle Seat For 398188

480036

replacement procedure
Hello Most people have had success removing the seat with a sharp piercing tool....like a dental pick. It has to be long and sharp and thin to get to where the seat it. After removal, the new one is "dropped" into place in the fuel cavity and pressed in. You will need to improvise and see what means you have available to fit something inside the fuel tunnel to PRESS the new seat into place. Or, you can utilize the methods used here.
