Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
How old is this machine? Is it a new machine? Or an old machine with really low hours or use?
My first thought would have taken me to the fuel cap as well.
This fuel system most likely has an emission friendly vent system which means that it has a carbon canister vent system, if you happen to overfill the machine or get a lot of fuel splash the carbon canister will get fuel in it and can cause this type of issue. You can do one of two things if this is the problem: 1. Allow the carbon canister to dry out, it may take several days to totally dry out and run properly. 2. Replace the carbon canister, which can be rather expensive depending on which style was used.
The amount of fuel that you have in the tank will also determine how long the machine will run without issues as well. If the tank is near full then it will run a shorter amount of time than if it is half full or near empty. You have to be really careful to not overfill or get on to much of a slope with these new fuel systems or this is going to happen often.
I am sorry I had to step away for a little bit.
It could have more to do with the amount of fuel that was in the tank when you started the machine. If the tank was full it would run a shorter amount of time, if it was half full it would run longer before creating an issue. It does sound like the fuel tank isn't venting properly and is causing a vacuum inside the tank after running for various times which is causing the engine to stall or die. When you remove the fuel cap you remove the vacuum which will allow the fuel to flow again and it may run a short amount of time or it may run for two hours depending on the amount of fuel in the tank and how long it takes until all of the air is used up inside the fuel tank and then the vacuum comes back and will not allow fuel to flow out of the tank again.
The carbon canister will be located in a line that comes off of the top of the fuel tank and normally runs back to the intake on the engine. If it is a matter of having fuel in the canister it will evaporate in a couple days and the problem will solve itself, if you need to replace it before that then you will need to contact Cub Cadet. I would recommend checking with a local servicing dealer since the machine is so new with very few hours on it, it should be a repair that can be done under the warranty.
Thank you it has been a pleasure to assist you.
