Push mower will not start....

[Two-Stroke]

After I took the carburetor off there was a tube sticking out, it had nothing in it and looked completely useless. (in the photo) so I took the tube and the cover off and it looked even weirder! What is it? should there be something in the tube?

That tube is the crankcase "breather". When the piston goes up and down it displaces air and that tube gives the displaced air somewhere to go. If the tube is unblocked it's OK.

Two-Stroke has you heading the right direction...
On the opposite side of the carb, you should find a small plate held on with 2 or 4 screws... that has a small spring and diaphragm under it... That is the fuel pump on this type carb... Remove the cover plate, and replace the little pump diaphragm, note the direction the spring is placed...

With the fuel pump open you will be able to blow through the pick up tube... If not spray carb cleaner into the fuel ports inside the pump... :smile:KennyV

if this carb is without the side mounted fuel pump, it will be simular to the one in this video...

Yes, it has no side mount. I soaked the part that goes and sucks gas from the tank in carb cleaner overnight, I will see how that works a little later
