Re: 1999 115 hp johnson outboard
If the engine has fired for a split second it will often cause the starter to free spin until you release the key and then turn it again
this is te explaination for your starter disengaging and acting li its spinning freely......(well it is sinning freely) your motor is ALMOST startin ,and the start bendix senses his and pulls out.....but you need a tune up, becaue the motor wont say started.
#1 make sure you have a fully charged battery with good clean connections and are getting all the batterys juice.
#2 Prime the Bulb till I is hard.( important)
#3push in and HOLD hey7-8 seconds
#4 push in ad turn key to start
the is no FORCED "squirt" of fuel.....when you prime the bulb, you pressureize the fuel system, then when you push the key in, you open the door for gas to enter DIRECTLY into the manifold.
if the motor fails to start after few tries, you may need to prime AGAIN...to RESTORE pressure
