I bought a used 2006 Mecury 9.9 HP 4 stroke outboard motor. Am new to outboard motors, but I am having some issues with this motor. When I prime the motor (either with the priming bulb on the fuel line from the tank or the priming bulb on the motor), gas will eventually leak out of the carb. I replaced the fuel line from the on-board priming pump to the carb, but it still leaks when I press the priming pump (although not at much). Is this normal for outboard motor engines? I have also found the gasket between the carb and intake manifold not correctly in place. I am wondering if the carb needs a rebuild - are there carb kits available to do this?
The engine also has a tough time idling - if the idle is set too low, the engine stops when put into gear unless you give it lots of gas, which makes shifting into gear a bit traumatic. If the idle is set too high, the engine surges/hunts - cyclically revving up in speed and then coming down in speed. I am wondering if an orifice is partially plugged to cause this.
Any advice appreciated.
