I can run my zero turn mower all day at low or middle

Customer Question

I can run my zero turn mower all day at low or middle throttle but when I run it at high it starts to die like it
s running out of fuel. The engine is a 25hp Kawasaki snapper. I've changed gas caps, put on 2 coils, replaced the carb solenoid and those actions don't help. I need help.

The mower cranks up fine and runs with throttle in lower setting with no problem.

There is a possibility that you have a clogged high speed jet in your carburetor. This could explain why your engine seems to be running out of fuel, when you are operating your engine at higher rpms.

Expert:  Donald replied 1 year ago.

I do have some suggestions for you.

Customer: replied 1 year ago.
Good what are they?
Expert:  Donald replied 1 year ago.

It is very likely that your carburetor needs to be cleaned, but I would like for you to try something first, that may work for you. There is a fuel additive called Mechanic In A Bottle that have worked really well for many people. I suggest that you replace your fuel filter, and add some Mechanic In A Bottle to your fuel.

Try this first, and if it does not resolve our problem, then you will need to consider cleaning your carburetor.

Expert:  Donald replied 1 year ago.

Please click on the link above. It will open up the website for the Mechanic In A Bottle.

Expert:  Donald replied 1 year ago.

You have already replaced your fuel shut off solenoid, and you are getting fuel to your carburetor. So, this leads me to believe that your carburetor is at fault.

We can continue from here.

You can purchase Mechanic In A Bottle at your local Tractor Supply Co., or Home Depot.
