is the timing adjusting? is the fuel bulb hard? are the carbs clean? is the fuel good?

Re: 2001 20hp yamaha 2 stroke

fresh fuel, carbs are clean, doesn't seem to be sucking air through fuel line anywhere although the fuel bulb does seem to vibrate/clicking noise when motor is running? not sure how to adjust timing...I was wondering if the cdi's break down on these motors...
