Ok new here haven't gotten any answer in the Tecumseh section trying here

Its a sear edger with a 3 hp Tecumseh  I put a fresh carb on a couple of years ago  cleaned what ever dirt was in bowl & checked gas line & tank  ok been doing small engine work for 60 years & some of it in a shop  never has a surging problem like this no matter how I tune it I can't get that sweet spot of smooth running  it run fine if I hold it at any speed but on its own it surges  the float is level with the base & I sprayed in all the mixer screw openings  any help in this section ?  Thank you

Surging is usually from lack of fuel, especially in the low speed jets.
 
Quote " cleaned what ever dirt was in bowl " .  A clean bowl is obviously important BUT the inner passages of the carb has to be cleaned.  Those little spaces/jets are what clogs and causes issues. (I'm not sure reading you post if this was done)
 
I'd pull the carb apart again, use carb or brake cleaner preferably with a jet cleaner or air compressor.
 
The tool I was referring to: https://www.ebay.com/itm/142244693542?hash=item211e71c626:g:RLYAAOSw0vBUi4bi
 
An incorrectly adjusted governor can also be the culprit. 
Taryl, "the character", once past the antic's, is EXTREMLY KNOWLEDGABLE and shows how to adjust it:
