I can squeeze the bulb all day, and it will not harden. I also can hear what sounds to be air coming from the carb area when I am pumping on the bulb. <br /><br />The bulb and all fittings are new, fuel tank is new, it is properly vented, and everything has hose clamps on it.<br /><br />The motor will run fine, it you choke the **** out of it to get the gas to the carb.<br /><br />Motor is a 1974 65hp.
