Hi All, I have an older 15hp johnson,model j15rlcrm. We just put in a carb. kit and now it won't prime unless the gas line is off the motor. Then the bulb will get hard, connect to motor and it runs fine. Thanks for your help. Tim
Puzzled by this but i think its the valve at the outlet end of the bulb thats causing the trouble. New bulb will sort it if i am right but wait to see if anyone agrees with me.
