weed eater engine will only run on full throttle

[lerick]

ok this is what happened i had the weedeater runing like normal with the airfilter off to get more air and then the engine made a pop noise and some steam ( or something else) came out of the carb and i started it back up and it ran but did it again and i let it sit over night and not it only will run on full throttle so i took the carb off cleaned it and blew some air threw the jets see if it was cloged and that didnt work and so i soaked the carb in gas over night and ima go try that out but could anyone know the problem? its a homelite weedeater engine 29cc? i think

Removing air filter just gets you more dirty air.
Low speed channel is probably clogged.
Could be bad diaphragm.
Air filter performs a service.
To remove it senseless.

where is the low speed channel at?

Just as a quick easy test, see how it runs with the filter reinstalled. I've ran across some small engines that needed the air cleaner instaled to run corectly. (ps: these probably could of been re-jetted to run better w/o the air cleaner)

There should be two screws by each other. They control your low and high.
