If the bulb won't get hard you have a leak, when the motor is running you will be sucking air.

THIS^^^ for sure.
Have you checked the carburetor gaskets? I had a Johnson GT 150...the same motor as yours. The ethanol in the gas had softened the carburetor so much that they leaked.
Another thing...those were cold hearted motors. They were a PITA to start in the morning. But, once you got them going, they would start great all day. An old timer showed me this trick and it works for any old carbureted motor. First, pump the bulb tight (once you get that problems solved). When you back in the water, lower the motor until it's level. Chock the motor by pushing the key in and slowly counting to 10, but do not try to start the motor yet. Once you reach 10, start the motor. It should start much easier using this method. Let the motor idle for about 20 seconds until the rpms drop. Back off the trailer, tie up, park you truck!

My buddy had a Johnson and had to start it up just like Jeff said. Once started that thing ran great.
Done a compression check yet?

Like Jeff said, had a rude 150 and was told by a old boat man to chock it thjat way,never a problem anymore
