    Motor starts OK take off is great but after a while it appears to run out gas, if I squeeze bulb it will takew off again. I replaced bulb and it appears to be getting worse each trip. Don't know what to do?​

    Sounds like you need to rebuild/replace the fuel pump. Might also want to check the carb/carbs while your at it. when the motor is running slow the fuel pump is keeping up but once you get the rpms up it cant supply enough fuel so when you squeeze the bulb you are just helping it out and motor takes off again. Check all fuels lines for leaks also

    Good post James.

    A spark and compression check is where you should start, then go on from there.
