My problem ended up being the spring on the reed valve being weak.But at the same time and while I had already had my carb broke down I took a can of carb cleaner to it and cleaned it. In order to replace the spring on reed valve you will have to buy a new one, but don't worry I only payed about $6.00 for mine. You may also look into replacing your primer bulb if you haven't already because may allowing air to build up in your gas line while you are basically idiling.Once you get the carb straightened out you may have to reajust it again. If I might be able to help you again you may contact me at email@example.com.

I have a maintainance manual for this engine (I have the same one) with pages of wiring diagrams. What specific system/area are you interested in, I could scan in the page(s) and email them to you.

For the DIY boater it could be a number of possibilities - fouled plugs, old fuel, improper air fuel mixture or dirt in the carburetor.
Pull the plugs and check the color of the ceramic. Light tan is good. Dark and oily is an indication of misfiring, fouling and too rich oil or improper air mixture. Make a note of which plug came from which cylinder. If they're all about the same color (dark) replace them all. Properly set the electrode gap and install the plugs.
You could try spraying the intake with carb cleaner like "Gum Out"
to clean out the carbs too.
Drain and clean out the sediment bowl of the carb(s) test again.
If cleaning sdoesn't take care of the problem then you need to Reference a Mercury marine manual for initial air screw mixture settings, ie: air screw location and how many turns out are recommended.
Air fuel mix is adjusted by a screw on each carb. No more than a 1/4 to 1/2 turn should be made at a time. Test again.
Also when you store the motor for the season, get some "Gas Stabilizer" for the fuel tank. Mix the recommended amount in a full tank of fuel, run the motor for several minutes. This step will put the stabilized fuel into the carbs for storage.
Hope this helps.
