I have a craftsman mower, walk behind that has been fine up till now.
Today as I was sidehilling with the carb on the downhill side it starts spewing gas out the air filter and shuts down
I let it dry out, restart and while mowing with the carb on the uphill side or on the flat, it is fine, switch over so the carb is down hill and it starts to run poorly, gas comes out the little tube in the air filter ( I removed the air filter to see where the gas was coming from) then it dies. Takes several pulls to restart unless I let it set for a couple of hours.

What do you think the problem is?
Float stuck? Should I give it a technical tap with a screw driver handle?

Is it more than this and going to require the carb be taken off?

No one has a clue?

Sorry, just joined the other day. It depends on what engine you have to be of much help, but yes, in general, you will have to remove the carb, or at least drop the bowl off of the bottom.

Give us some model numbers off of the engine and the mower, and we will be able to go into more detail.
Thanks,
Fish

Things get worse before they get better.

After mowing the other day, and having it cut out on me 1/2 way through, it just leaks out the carb until the tank is empty.

Sounds like a problem with float valve/seat or the float. Any gas in the oil?

No gas in the oil.

Gave it the "technical tap" with a screwdriver handle, no fix.

Guess I'd better just pull it apart and see what's up.

Should I just pull the bowl and see if the float moves freely or should I pull the whole thing off.

The carb will come off easy enough, it's removing all the shrouds to get to the inside nut that is the pain.

I would definately pull the carb with the issue your having and give it a good cleaning. Paying particular attention to the float valve, seat, float and float pin for debris/gum.
