I have a 115 HP 4 cyl (S/N: OC294292). The prime bulb goes empty on me. I pump it up and the motor starts fine and runs full throttle for a short period and then rpms drop off and sometimes I get a additional surge but then the engine kills. I replaced the prime bulb, and the fuel filter up in the motor still no help. Now I am trying to replace the fuel connection to the motor but I cant seem to find the correct part to fit the connection. So far I have tried a TEMPO P/N: 486MFC and a 481YFC and neither one fit. Can anyone help me as to where to find the proper connector to put on the fuel line or any other suggestions as to why the motor would act like it does? It always starts fine after pumping up the prime bulb and it idles fine but under full throttle it will kill everytime. I dont see any leakage inside the motor near the fuel pump or fuel filter areas. HELP.

If the primer bulb is collapsing your problem is in the tank either a anti syphion valve is sticking or the screen is plugged
