Small Engines (Lawn Mowers, etc.): carb, fuel valve, fuel flow

Question
soaked  carb  in cleaner can not get it to idle

Answer
hi leroy

has this  carb been siting a long period of time and gone green ?

does it have any bluish/ green particulates in it  and  carb  metal looks  pitted   ?

if this carb does have  bluish or green particulates in it  and looks pitted  
suggest second hand carb.   because carb metal( antimony) is being attacked  and breaking down
pulling these particulates out of  metal body  
  
have you blown out all  air bleeds and nozzles , check idle and progression port outlets
checked bowl vent, and  main jet for obstruction   all must be clear and no restriction

is flow from tank to carb good,  does the  fuel valve / float shut off the fuel flow?

is the idle screw turned in far enough to hold it at an idle ?

is spark and compression good ?

recheck carb


cheers hope it helps
