Question about Craftsman 17.5 hp 42 in. Deck Lawn Tractor - CA Model

1 Answer

Riding mower fails to get gas fast enough to keep it running; floods when off.

That's pretty much it. I cannot fathom how i must have adjusted the richness screw to make it do this... After a few seconds of being off, the 8 horse Briggs & Stratton starts on the first pull. It runs beautifully for a short time--till it uses all the gas that has trickled in from the tank. I left it over night and the whole gas tank had emptied into the chamber--albeit too slowly to have kept it running when I wanted to cut my grass.

Sounds like you better check your oil level to make sure this engine isnt overfull now with fuel - if your tank drained, the needle and seat may be bad or else the brass float is bad - get back to me and well get it running right

When im riding engine cuts out like im out of gas then dies ,with full tank after a few minutes will restart

Check the fuel filter. If it is mostly clogged, you will get fuel through, but not fast enough to keep going.

If it is pretty old, the fuel lines might be ruined by ethanol in the gas. The inside of the old rubber lines looks like the rubber has melted. New fuel lines are made of material that is resistant to ethanol. Anyway, fuel should flow like water in a pipe. If it is sluggish at all, replace them.

Clean the carburetor. It sounds like the float is not moving right. It runs out of gas and doesn't refill right away. After it sits for a few minutes, it slowly refills, then you can go again for a short time. This is a shot in the dark for this problem, but I have solved 90% of running problems by just doing a quick carburetor cleaning.

John deer flooding out went engaging deck

If this is an older mower that has carburetor adjustments , turn the large needle valve counter clockwise 1/8 of a turn., and see if the mower runs with the deck engaged. If there are no adjustments on the carb. It may need need cleaning, and the gas filter may need to be changed. You can place 1/3 -1/2 can of carb & fuel system cleaner in the gas tank and run the mower. If this does not help, please forward info on the mower - Model #, serial #, and Model/ serial # of engine, which is usually on the ehgine shroud.

Mower cranks with throttle in choke. after cranked and throttle moved to fast or any other position. The mower dies as if someone turns it off??

Ok I assume what you are trying to say is that once it starts with the choke on and you turn the choke off it dies.
This behavior usually means that the engine is leaning out. This means that it is not getting enough gas. Often if you put it back to choke fast enough it will keep running though very roughly.
The problem is the main metering jets are plugged or there is some kind of obstruction in the carburetor. This is assuming of course that the tank is full of gas and the fuel filter is clean.

Have fuel to carb but engine wont keep running? help

Time to clean out the carburetor. It sounds like the needle valve is not opening, the jet is clogged, or the float is miss adjusted. May have a clogged fuel filter, allowing enough gas to start but not enough flow to keep it going.
Good Day.

Murray riding mower 12.5 hp briggs & stratton spitting oil & gas out of carb & muffler when trying to start

Drain oil... it is full of gasoline due to a bad float pin and rubber gromet in your carb. When your float pin and gromet fail, gas just keeps flowing into your carburetor, eventually flooding your motor with gas and oil mix.
