    hello
    I have Cub Cadet LTX 1050 VT

    Sv720
    23 HP
    Shaft ? Vertical
    Cylinders ? V-Twin
    Cooling ? Air

    the problem is - no gas is going into the engine.
    I empty the gas filter that connected to the fuel container and I do not see that the gas filter is filled again with gas.

    This led me to think that the FUEL pump does not work OR something else.

    what do you think?

    I cleaned the fuel pump with air and the back of the fuel pump came out. (maybe I broke the fuel pump).

    what cause the gasoline to go into the Carburetor?

    Thank you very much

Hi again.

Ok before I go on you can download a free Kohler service manual for your engine here:

http://www.kohlerengines.com/onlinecatalog/pdf/tp_2574_a.pdf

If you have removed the input fuel line just after the filter and there is still no gas it leads me to believe one of 3 things
1. That the fuel tank vent is not open
2. The fuel filter is clogged (100 hr replacement interval)
3. The fuel tank outlet has debris in it,
Have you removed the fuel hose before the fuel filter and checked for fuel flow?

The carb itself has a fuel shut off solenoid on the very bottom of the carb. You can try putting battery voltage on this solenoid and see if it starts normally. If it does then there is a problem with power to the solenoid some where between the ignition switch and the solenoid. ( I just doubt this is the problem because you can add gass to carb and it starts )

This carb also has 2 jets in the bowl area a slow jet located under a rubber plug and the main jet (center) The slow jet can be clogged but again this would usually result in the engine not idling.

From what I am reading per your statement: "I empty the gas filter that connected to the fuel container and I do not see that the gas filter is filled again with gas."

Every thing there is BEFORE the fuel pump. This still has me thinking
1 filter
2 tank outlet clog / restricted
3 fuel vent problem

Pull off the fuel line "after" the fuel filter and remove the fuel tank cap. If you get a gush of fuel you have a vent problem.

Lastly the fuel pump diaphram is pretty fragile. Hopefully you did not damage it when you blew air into the fuel line. (been there done that!)

For on line parts diagrams you can use this link:
http://www.jackssmallengines.com/help.cfm Left side of page middle of page
(drop down menus)
kohler engine
courage series
SV720S
then select your model engine that ends in 0010 - 0032

Bottom line the problem appears to be before the engine from what I see.

How to replace drive belt on cub cadet 1050

Fairly easy to replace once the deck and the electric PTO are removed just make mental notes or rough of the belt path before removing the old belt. One thought if I remember correctly this uses 7/16" belt and a 1/2" width will not work due to the tight clearance at the engine pulley so stick with OEM belt.

Hello I have Cub Cadet LTX 1050 VT Sv720 23 HPEngine Kohler

This situation is just a clogged fuel line IN the tank. It happens. Yeah, stuff that gets In builds up in the line an elbow and plugs it up. Just pull the connection out of the tank and clean it out. I have even found plastic bits clogging the line on mine. I have a LT 1050 also. And a Cub ZT I just love.
