I have a toro with 11.5 hp kawasaki
It ran well last year but did sputter a little when on low idle.

when I started it this year it will only run full throttle with choke closed
and sounds fine.

if i back off the throttle at all it will stall out at once.
the fuel lines are not blocked.


any ideas?

The carb needs a good tear down and cleaning with carb & choke spray cleaner, There are some blocked passages/jets.....

i don"t have a reply more like a question! sounds like we may have the same mower> what year is you mower? i am having the same problem

It doesn't matter what year or brand unit or engine you have, If you have the same problem do the same thing to your carb.....

Restrorob has the most likely answer for you. Carburetor gummed up from sitting idle for the season. It should be taken apart and thoroughly cleaned inside, with solvent based Carburetor/Choke Cleaner. Fuel/Air mixture is off, due to blockages inside Carb. The indicator is the fact that it runs better with the Choke engaged (cutting down on the amount of air getting through).

my thing is that all the stickers and codes are gone on the engine ie: hp and engine numbers> i was looking for more info on the jet size

 

[Restrorob]

Do you know what brand engine it is ?

kawasaki> i was told it may be a 12 hp

Look on the side of the engine block, There should be a white bar code label with engine model and spec numbers. These do not normally peel off, One would have to scrape it off for removal.
