Question
exmark mower stalls out under a heavy load. turn blades off and put in park starts right back up no problem . replaced gas lines , filter, spark plugs. still having problems. whats left?

Answer
Hello Eric:

Send me the Model and Type Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. Depending on the Engine Model, it May be the Carburetor Requires Adjusting or Cleaning. From your Description, it Sounds like the Carburetor Jet is Restricted and Does Not Allow the Proper Amount of Gas to the Engine When it is Under a Load. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
