Lost my main jets while cleaning old gas from carb.
I removed the fan shroud, the carb/manifold as an assembly,turned the carb upside down and removed the fuel bowl. I replaced only one jet. Not until this moment did I discover their were two jets in this nikki carb. I now have a second jet ordered and will install it Friday,hopefully. These jets are two different part numbers as one is a left jet and the other is a right one. Be careful when opening the fuel bowl as these jets are held in their bores by small O-rings, and nothing else. The brigg's and Stratton part numbers are 791501 for the left jet and 791502 for the right.

Gas leaking from tube breather
First I opened the top of the mower to expose the housing cover. Secondly I removed the four housing bolts to remove the housing cover from the mower. Next I removed the tube breather and installed the new tube breather and replaced the housing cover with the four bolts previously removed and closed the top of the mower. I filled the mower with gas to check for leaks which weren't any leaks. I proceeded to mow the lawn with ease.
