my lawn mower lost power, it starts but does not have the power it once had why?

First check the air filter.If thats fine thenits probablya dirty carburator.if youneed info on how to clean your carb feel free to email me

i might think of it quite no longer likely, yet examine the air clear out. The mower could be working too rich. With the mower as new as that's, I doubt if the clear out might already be plugged, yet you under no circumstances understand. that's decrease than guarantee, so take the mower to a Toro qualified restore shop. stable success.

Is it an old mower? If it has not had a tune-up in a long time, the ignition timing may be off. This would cause a motor to lose power but may not stop it from running.

its the carburetor diaphragm.trust me.had this problem and once replaced works as new.google the model number of it or find a repair shop near you and tell them the model #

if it revs up and slows back down it is the carburetor diapraghm.i dont use the air filter because they never work anyways.http://www.google.com/search?client=firefox-a&rls=...
