You say it bogs when you "hit the throttle", have you tried doing that while somebody is squeezing the primer bulb? here
I doubt seriously it's that arm. My bet is it's sucking air somewhere or possibly the fuel line is collapsed. Do you have another fuel line you could try? more

Honda outboard motors are among the finest on the market. Before operating a Honda outboard motor, read and understand the owner's manual and warranty policy. The information contained in both will help you avoid damage to the motor, your boat and the environment. Honda outboard motors require regular maintenance and should be taken to a Honda marine dealer for scheduled appointments. However, if a warning light comes on, there are things you can do on your own to address the problem.
If the programmed fuel injection light or buzzer comes on, your outboard motor has a faulty system and requires professional maintenance. If the alternating current generator light or buzzer sounds, you have a battery voltage problem or a faulty system. If the problem originates with the battery, you can jump-start the engine or replace the battery. If the system is faulty, the engine will have to be taken in for routine maintenance.
If the overheat system activates and the light comes on or the buzzer sounds, your engine might lose speed if the boat is moving. Another symptom of an overheated engine is that engine speed will not increase when you open the throttle. One possible cause of an overheated engine is a clogged water intake port. This can be remedied simply by cleaning the water intake port, which is located slightly above the propeller. An overheated engine can also be caused by a spark plug that has an improper heat range. Before attempting to change a spark plug, you must allow the engine to cool; at that point you can remove the engine cover, take a spark plug wrench and 17 millimeter wrench from your tool kit and remove and inspect the spark plugs. Replace any spark plugs with noticeable wear or cracks. Your outboard motor might also be overheating because of a faulty water pump, clogged thermostat or water line or a problem with the exhaust system. All of these problems will require professional knowledge, and you should not attempt to fix them on your own unless you are confident of your engine knowledge.
