On the front of the carburetor it has a diaphragm fuel pump and after I start it theres two little holes were gas comes slowly leaks from. The holes look like factory holes. My other twin has the same thing but doesnt leak

Today I took the fuel pump apart and didnt see anything wrong so I kept looking and noticed that the diaphragm was in backwards. So I flipped it around and it stopped leaking. Very Happy
