SWAG......check valve in the bulb is not sealing or floats in the carb are not sealing and holding.......which should cause flooding and hard starting.

My best guess.

Re: fuel priming problems

When does it lose its prime? While its running? Does the motor die or the bulb just gets soft. The bulb will get soft while the motor is running. Thats perfectly normal.
