The lawn mower sat for over a year with no use. It sounds like it wants to turn over - just wont fire. I think old gas may have gummed up the carb

Hello. Thank you for choosing Just Answer. I will be happy to assist you. Do you have some carburetor cleaner in a can?

Customer: replied 1 year ago.
Nope. Was going to go get some. Got this mower from my dad so this is my first time servicing it. I cant locate the carb. Its a 2006 Cub Cadet LT1046... Can you help me locate it?
Customer: replied 1 year ago.
Dont see it on any of the parts manuals
Expert:  Donald replied 1 year ago.

I can help you locate it, What brand is your engine? What are the model numbers for your engine?

Spec # *****
Expert:  Donald replied 1 year ago.

Thanks for these numbers. Click on the link below. Your carburetor is behind your air cleaner housing.

Customer: replied 1 year ago.
Okay I found it. So just spray into that opening - or somewhere more specific?
Expert:  Donald replied 1 year ago.

Glad you found it. The purpose of the carburetor cleaner, is to see if your engine will either start up and continue to run, or if your engine will start up and run briefly, after you spray carburetor cleaner into your carburetor.

Expert:  Donald replied 1 year ago.

If your engine will only run briefly, afterwards, then I would check to make sure you are getting a steady flow of fuel to your carburetor. If so, then you will need to give your carburetor a really good cleaning.

Expert:  Donald replied 1 year ago.

The old gas has likely contaminated your carburetor, and clogged either your main jet, or the small fuel passages inside your carburetor.

Customer: replied 1 year ago.
Would you recommend a carb and choke cleaner spray (Gumout brand) ? Or other - something I can pick up at Home Depot
Customer: replied 1 year ago.
Or Gumout starting fluid?
Expert:  Donald replied 1 year ago.

I prefer using carburetor cleaner for this purpose, rather than starting fluid. The brand does not matter.

Customer: replied 1 year ago.
Okay thanks will run out and get some
