Hi guys I picked up this lawnboy and it’s in good shape. Needing a battery and key for the lecture start otherwise complete. It doesn’t start and I’m assuming that this might be a major issue

I cleaned the gas tank and fill with gas. Attempted to start without the filter on and gas is pouring almost directly out of the red breather tube. What is wrong and how can I fix this

I'd guess the float or the float needle valve inside the carb needs attention. A really small piece of something in that needle valve will cause the overfill.

Thanks. I’m going to tear it down and have a friend run it through an ultrasonic

Some of the newer carbs have a rubber insert in the recess for the float valve. If the needle has a metal tip look for that.

The engine is a Tecumseh, if you want to look for stuff on youtube on the carbs.
If the float is brass, shake it to see if there is fuel inside.
