"Hi I have just purchesed this

"Hi I have just purchesed this boat and motor ran the boat for about 15 miles, ran a little ruff, had problem with vro. I installed new vro. the motor when running at low to about 3500 rpm will pop or miss.rpm will very about 200 rpm. it may do it at wot but I do not notice it.I did not change the pulse limiter fitting.also the spark dewl adjusting knob was laying at the bottom of the case. I screwed it back on to the set screw wheel.
any thoughts.
thanks Billy"
