Easy repair
The part was the correct one. Once we replaced it, the mower started like a new one.

Just what I needed
Mower was starting hard cold, I replaced the bulb and noticed that it still would not prime correctly, I cleaned and rebuilt the carb - still no priming. I replaced this part and it did the trick.

Remove the existing air cleaner base, installed the new air cleaner base and gasket. I used the new gasket and placed it on top of the old gasket to double up. I did this so the air cleaner base would get a proper seal so the primer bulb would actually function properly. After doing this, I primed the engine about 4 pushes on the primer bulb. Pulled the starter rope 2 times and the engine fired right up on the 2nd pull.
