Hello rbronniman:
I Understand you have Cleaned the Exhaust Port, but Did you try Running the Engine with the Muffler Off the Unit?
Sometimes the Muffler or Spark Arrestor Screen can be Restricted Also.
If the Muffler and Spark Arrestor are Clear, then the Problem is Either Worn Rings, Bad Carburetor Mount Gasket, Improper Spark Plug Gap, the Carburetor Metering Jet is Not Operating Correctly or the Internal Carburetor Filter/Screen is Restricted and Requires Cleaning/Replacing.
To Correct this you need to Soak and Clean the Carburetor.
>>The Following is a Basic File I Made for Cleaning Carburetors. Any Input is Appreciated. Even though the Carburetor Looks Clean, the Internal Passages May be Restricted with Varnish that Gas Causes to Build Up over Time.
>>Spray Cleaners Remove this Varnish in Layers, so Soaking is the Only Sure Way to Remove ALL this Varnish.
>>I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning.
>>Remove Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed.
>>If you are Able to Remove and Disassemble the Carburetor and Keep the Gaskets Intact, then Usually these Gaskets can be Reused. The Only Parts you May Need to Replace are the Needle Valve and Metering Pump Diaphram.
>>The Metering Jet Diaphram Dowl should Just be Touching the Metering Jet Actuator.
>>The Metering Jet is Under the Carburetor Plate with 4 Small Screws Holding the Cover Plate to the Carburetor Body.
>>Check the Internal Screen Filter for Restriction also.
>>If you Order a Kit, then Replace All the Old Components with the New Ones in the Kit even if the Old Parts Look Good.
>>Once Disassembled, then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts.
>>Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage. Then Blow Out the Passages with Compressed Air.
>>***(Do Not Use High Pressure Air for the Zama Carburetors, they have Check Valves for the Primer and these are Usually Blown Out of the Carburetor if Not Careful. Allow the Zama Carburetor to Set on a Drip Pan and Dry)***.
>>****All the Carburetor Adjustments are the Same for Lawn Mower and Trimmers.
>>If the Main Air and Idle Air Mixture Screws are Side by Side on the Side of the Carburetor, then the Idle Air is Nearest the Engine.
>>****Turn the Idle Air and Main Air Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Holding the Throttle Full Open, Start the Engine. Turn the Main Air Mixture Screw Clockwise Until Proper Revs are Obtained. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs. Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required. Now Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
>>If you have Questions, Please Ask. The links above Provide Good Directions on Cleaning the Carburetor. Make sure you use an Compressed Air to Blow through all the Carburetor Passages to make sure they are Clear.

This is without question the most common problem for this type
product. The reason the unit shuts off is that the carburetor can
not deliver the proper amount of gas for the amount of air that the
engine needs. If the carburetor is less than two years old you
might just need a carburetor adjustment but because of
environmental regulations, the government does not want you to
adjust your carburetor. To adjust current carburetors you will
need to have an authorized servicing dealer remove the limiters on
the carburetor or you will need a special tool to make the
adjustments. If your carburetor is more than two years old you will
most likely need to clean and rebuild the carburetor. The
carburetor has two functions in supplying fuel to the engine.
There is a fuel pump side of the carburetor which takes a pulse of
air from the engine to supply a small amount of fuel to compensate
for the extra demand when you pull the trigger. The other side of
the carburetor is the metering side.
This side meters the fuel for the high speed needs of the engine.
When an engine starts and goes dead it is because the engine is
getting just enough fuel to start but not enough to keep the engine
running. The cause of a lack of fuel can be many things. It can be
a clogged fuel filter, it can be a crimped fuel line or a cracked fuel
line allowing the fuel system to **** air. Inside the carburetor it
can be hard or stretched diaphragms, a clogged inlet screen or a
build up of trash and varnish in the carburetor. To properly
rebuild a carburetor you need to remove the carburetor and
purchase the correct kit for the rebuild. disassemble the
carburetor carefully making notes where each parts go. Once you
have the carburetor disassembled clean it by soaking it in
carburetor cleaner for a few hours. Use canned aerosol
automotive carb spray cleaner to fill a small glass jar with enough
cleaner to submerge the carburetor. Use a jar with a metal lid so
you can gently agitate the solution occasionally to make the
process more effective. You need to allow the carburetor to soak
as long as it needs to remove all visible deposits. After the
carburetor is cleaned allow it to dry and reassemble. The rebuild
kit will not include any mounting gaskets or intake gaskets so you
will need to purchase them separately. Hopefully this will solve
your problem.
Poor quality gasoline can be the major cause this problem. I
recommend that you always use white gas if it is available in your
area. If it is not available try to find the gasoline that has the
lightest yellow color. The darker the yellow color the more sticky
varnish deposit that will be left behind. And totally avoid gasoline
that has a orange color. The darker the color the more problems it
will cause. For most of the country the only white gas available is
Amoco which is now sold as 93 octane at BP stations.
If you found rust or corrosion when you opened your carburetor,
then you probable have had water in your fuel at one time or
another. To check for water in your fuel use a crystal clear bottle
such as a soft drink bottle. Water is heavier than gasoline and the
water will go to the bottom. It is also beneficial to filter your fuel
before you put it into your machine. A cone shaped coffee filter in
a funnel is perfect for this.

I would start by checking the condition of the fuel filter and fuel lines and progress to the carburetor from there. Make sure muffler is clear and air filter is not clogged. Your symptoms have all the signs of a dirty carburetor. Post back after checking condition of fuel tank, fuel filter, fuel lines, muffler, and air cleaner, and spark plug also.
