Abnormal Engine Performance

[Charles Demyan]

I am experiencing motor cutout after extended periods running flat out. I have a 1967 Merc 65 hp EL. Retarding the throttle to idle causes the motor to cut out completely. What could be causing this problem? Any advice would be appreciated

Check the fuel flow. Does squeezing the bulb help? Do you have a fuel filter that may be clogged? Could also be a fuel pump.
