it sounds like you have compression but the fuel air mixture is out of setting. This could be due partialy to a stuck fuel needle or mixture needles that are worn or out of allignment. If you could give me the model # on the unit i could help with the type of carb and the inital settings on the mixture needles.

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please do not forget to rate me, Thanks
Good Luck, I hope this helped

You have a problem with the inlet float, there is something holding it from closing totally.
When you cleaned the carburetor did you clean it with a cleaning solution such as lacquer thinner, this is used to cut the "varnish" buildup in the jets and needle valves of the carburetor.
Follow the directions below:
Remove your spark plug and check to be sure you are getting fire at the spark plug.
You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater is over a year old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.
Once you have your carburetor rebuilt that should solve your problem.

If your carburetor has sat for a few months with fuel in it, the fuel may have gone bad. Fuel turns to turpentine after a while and leaves light yellow deposits behind. These deposits will keep your carb. from working properly.You need to dip the carb. in carburetor dip for a few hours to get rid of the deposits. You can also take the carb. to your local parts store where they may do it for free.
You may also have to replace the gasket and needle valve too if it has been sitting. So basically, you need to do a carburetor rebuild. If the float sounds like it has liquid in it, you will need to replace it too.
