It's too lean.
First, check for vacuum leaks. Look for loose carb flange bolts, intake gasket leaks, anything that can cause a vacuum leak.
Then try opening the main jet adjustment, about a 1/4 turn at a time, see if that helps.
Next thing to check is fuel delivery to the carb. There is a drain plug in the bottom of the carb. With the fuel valve open, remove the plug, be ready to catch the flow in a clean glass. The flow should start as a full stream, as the bowl empties the flow will slow to a trickle, but should not slow to a drip. If the test fails, check the screen in the sediment bowl, there may be another screen in the carb where the fuel line connects. Try opening the fuel valve with the line disconnected from the carb, should get full flow. If not the problem is in the valve, or tank is contaminated with rust. Also look at what was collected in the glass. If it's contaminated with rust, dirt or water, those problems need to be addressed before servicing the carb.
If there is contamination in the tank, it will also be in the carb. Don't be afraid of the carb, they are simple and field servicable. A quick fix is to remove the bowl and clean everything up. Some spray carb cleaner and compressed air work well. Check the float level, check the jets for blockage, check the needle/seat for blockage. If the carb is in bad shape, a "comprehensive kit" will usually bring one back into service.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
