2005 50TR leaks fuel into exhaust when bulb is squeezed

[paddlewave]

Just noticed that motor starts to starve for fuel while running. I f I squeeze bulb a couple of times its seams fine. If I squeeze more than that it floods.
Is my fuel pump bad?

most likely.
it dumps fuel in the crankcase and runs out the ex port in the lower cyl.

That sounds like the case. Any suggestions?

after careful testing/eyeballing.
its a simple replace the pump.
if its the pump.

will do, thanks.

the pump was dry and crusty on the top( meaning the side closest to the cover plate that says in and out). the membrane appeared to be in good shape , no holes or tares,

I guess its the fuel pump. When I disconnect and squeeze bulb, fuel comes out where its supposed to get a pulse from cylinder. Is this the right synopsis?

Took fuel pump apart ,and found a tear in membrane that would receive pulse from cylinder case. Guessing that this would allow fuel to go into the pulse port then into cylinder case.
