Recently I purchased a carb rebuild kit and replaced all of the gaskets, welch plugs, and needle. The mower has spark and will run on starter fluid until the starter fluid is used up. Gas flows into the carburetor bowl. Gas flows with the float in the down position and ceases when the float is elevated. ( I believe this is correct) I am wondering what the next step in carburetor troubleshooting should be. Thanks for the help.

HI! Welcome to probably the best club on the internet for lawnmowers, to answer your question check to make sure the gasket between the carb and the block is sealed properly if it's ok then you probably will want to consider replacing the top and bottom crankshaft seals. Lawnboys are very particular about air leaks also did you take carb cleaner and clean all holes and parts, as well as readjusting your atmospheric adjustment needle?
