howdy, newbie boat owner here. i have a johnson 9.9 outboard on my sailboat(at least 10 years old), it has a black pushbutton on the motor that is used to start it, it always takes many trys to get it to start. the switch will do nothing for many pressigs, then it will eventually actually start starting. do i need to remove the top of the motor and clean(?) wiring/switches or do i obviously need a switch/starter/? i am sure this is an easy one- just don't know anything about 2 cycle outboards.<br />thanks, mike
