190cc Briggs and Stratton wont idle correctly

[Jonathan2003]

I've got the 190cc Briggs and Stratton push mower engine. I've replaced the piston rings and I've rebuilt the carburetor, but I cant get it to idle correctly it either idles to high or to low. It's got the autochoke system. Are there any adjusting screws that I am overlooking?

what's the model number?
it should be stamped above the muffler or above the spark plug, if OHV engine it should be stamped into the valve cover.
guessing it has manual throttle control?
