When I bought this motor 2 months ago it would idle but would not accelerate. I have cleaned and rebuilt the carb , changed the plugs , replaced the fuel line and tank, all to no avail. I then took the advice I received here and did the link and sync procedure. That didnt seem to help either. When I took the boat to the lake after the link and sync I adjusted the spark advance until I got the motor to accelerate but now there is way too much advance. The motor will start and idle fine and when given throttle slowly and smoothly it will accelerate up to a point then it wants to bog down again , but before it bogs it seems to be running at severely high rpms ,I cant check the rpms because the boat doesnt have a tach . From being an auto / aircraft mechanic though , it seems I have added too much advance but when I retard the timing the motor runs even worse. I am running the correct prop according to Mercury .
Anyone have any input / ideas ? They will be greatly appreciated.
