Q:

Mower starts after being primed but then stops 917388360 Craftsman Craftsman 6.25hp 21

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you’re having with the mower stalling. I know how frustrating that is.

It sounds like the primer is working since it is priming the engine enough to start and stay running if primed. This will be a carburetor issue. It’s probably dirty and needs to be cleaned. You probably have a clogged jet or a sticking needle.

I would pull the carb from the engine. With a full can of carb cleaner, a wire brush, and a bread tie wire to poke through and clean the main jet; I would recommend a very thorough cleaning. Start by taking off the float bowl. Douse it very liberally with carb cleaner, and undo the pin for the float, and remove the needle and float. Clean them very thoroughly with the wire brush and carb cleaner. Pay close attention to the seat the needle sits in and clean it well. Once clean, start brushing the carb bowl and body and make sure you get all the varnish out. It may take three or four brushings with carb cleaner dousing in-between. From there, take the straw of the carb cleaner and shoot carb cleaner through any little hole or passageway of the carb. Shoot out the throat of the carb and poke the main jet with the bread tie wire. You have to make sure you get everything the first time, if you leave anything behind, it’s likely to reclog once you have it reassembled.

Q:

Carburator Leaking 917388360 Craftsman Craftsman 6.25hp 21

A:

Thanks for the inquiry and for being a valued member.

It sounds like the needle is sticking or the float is fuel logged. You will need to open the carb up and check the needle and make sure it's moving freely within the seat. While you have the carb open, I would recommend performing a thorough cleaning and make sure there is no varnish. Clean the main jet and shoot carb cleaner through all the ports and passageways. 

For convenience, I have linked the model specific manual for this Tecumseh engine.
