Tecumseh 5hp fuel pouring from the carb

Noticed fuel pouring from the carb when I primed it this season. Didn’t inspect and saw fuel dripping from the bowl. Pulled the carb and noticed the bowl gasket was warped. Bought and installed new bowl and gasket. Started he blower back up and then shut it off went to restart and same thing again

Either the float is damaged or the float needle is not closing the flow of fuel even when the float is level (it may be that there isn't a good seal between the float needle and the float needle seal).

As DB130 said, check to see if the float is damaged or sticking. Once the float is removed,shake it to see if you hear liquid inside it, if so replace the float. Since you will have it apart to check, put a needle and seat kit in.

Does it do that if you don't prime it? The primer simply pushes fuel into the carburetor throat, which, based on your photos, looks like where the fuel is coming from. You may simply be overpriming . . . If it does this *without* priming, it likely is the float.

Thanks guys. I’ll pull the bowl in the morning and check to see if it’s still happening without priming. And if so I’ll look into the needle seal and the bowl

My bet is the needle is not sealing correctly and likely a new one is needed. I just had that happen on a Toro. You could look in the intake and see it full of gas. A new needle solved it.

One thing I have learned is that living richly is less about the net worth on your bank statement and more about the value of the lessons you offer those who want to learn from you.

While your checking things, check your oil to see if all the gas that has leaked through the carb ended up in the crank case with the oil. You may find the level WAY high on the dipstick or filler port. Also see if it smells like gas.

After an event like you have, I would change the oil as a matter of routine.

Work fascinates me.

Check condition of the main fuel pipe. Place fingers around hose, if they are black, hose may be rotten. Also check condition of the small primer hose going into carb.


I also had Chinese Carb leak. It was the tang on the float lever was bent to wrong way holding the float at bottom of the bowel. Straighten tang, check float is level, or use 5/32 drill bit to check float height.
