I have a 1988 mercury 90hp motor.The motor was in storage for 3 yrs.It was fogged and the gas drained.when I first started it ,out of the water,It seemed to run fine.When I put the boat in the water and ran the motor it ran fine for a short period of time, then it started stalling when I tried to idle in gear.I adjusted the carbs and turned the idle speed up.It would run fine for a short time then start stalling at idle speed again.Some one told me that the timing may need adjusting.If this is so how do you do this.
