Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please rate me, Thanks
Good Luck, I hope this helped

Hi , need help my mtd ride on mower was leaking fuel so I changed the fuel pipes it is now misfiring


if the fuel is leaking from the carb and its also misfiring then it could be that the carb is flooding. to cure this you will need to remove the carb, remove the fuel bowl off the carb,remove the float and needle valve and either blow out all the jets and air wys with compressed air or if you dont have compressed air try using carb or brake cleaner with a straw pipe in the nozzle to blow through the jets etc. check that the float and tip of the needle valve are in good condition before refitting them

Lawnmower leaks fuel from carb


It sounds as though your float and needle are stuck open or not closing properly, thus flooding with fuel. However it is hard to give exact fix/problem without a model number of the engine to be able to see the specs and design of the carb.

12hp brigg & stratton engine gas mixing with oil in engine block..when start engine runs high rpm can not idle & look like gas come out carb air cleaner overflows & flood out & stop engine...


Sounds to me like the float needle valve in the carb is leaking. This will cause fuel to over flow out of carb, and will even get into the engine oil. Check to be sure that float is not got gas in it the can go bad. Also check float adjustment. Check needle and seat very carefully for dirt or wear. Just the slightest bit of dirt or wear can cause it to leak. Hope this helps.

I have a Toro 1984-85 self propelled pull start lawn mower and I can get the fuel and air mixture just right it won?t stay started, it runs great but gets flooded now (I think), does anyone have the fix-it...


If the mower floods, it may be a float problem, if you have a carb with a float. New fuels can destroy older floats, dirt and gum can keep them from closing off the fuel supply. If you are comfortable taking your carb apart I would start there.
You will need the engine make and ID to get a manual.

Runs with choke out.. dies if pushed in. Will only run a short time then seems to flood. After that it will continue to leak fuel from under the air filter somewhere until the tank is empty... crazy....


Try rebuilding the carb. It might be your float is messed up. You can also get some carb and choke cleaner and take the sediment bowl of and clean everything in it. Give extra attention to the float and needle valve. They might have some build up that won't let it work properly.

Also your gas cap might not be venting properly.

The engine on my Sprint 375 floods when trying to start


Check the float in the carb. bowl for gumming and clean your carb.. If you haven't done so already. Or you can try running a fuel treatment through your fuel. That may help you with your flooding issues. Good luck.

Yard machine 139cc will only run short time with choke


Check the float and the adjustment screw on the bottom of the carb. Usually if the float stays up it will continue to leak gas and also will only run on choke. Spray some carb cleaner in there and try to get rid of any debri also try changing your air filter or cleaning it
