TB2040XP Troy-Bilt Trimmer - Instructions

emptied fuel from tank. pulled off the 2 fuel lines from the carburetor.opened the air cleaner door. removed the 2 torque screws that hold on the carburetor. removed the carburetor and air cleaner gasket. installed new carburetor and gasket and put back and tightened the 2 torque screws. closed air cleaner door and pushed the fuel lines onto the new carburetor.put some fuel in the tank. started the trimmer. runs great.

Removed 2 screws securing the air cleaner and carburetor to the engine using a T25 Torx driver. then removed the throttle cable from the carb.Then removed the o ring gasket from the engine and replaced with a new one and replaced the carb etc. Primed it and fired it up.Runs just like new.

The replacement of the carburetor, O-ring, and gasket was simple. I removed 2 screws that held the air cleaner and carburetor in place, swapped them out, and replaced the screws. What took longest was finding a piece of fuel line after breaking one of them. It was brittle after hanging in my garage for several years. I found some in my garage and replaced it. It took a few pulls to get it started, but ran very smooth.

Additional information: rather than mixing my fuel, I purchased 40:1 pre-mix fuel to prevent gunking up the carburetor in the future. I use it in my other trimmer and have not had any issues.

Removed and replaced both.

Y'all need to include the gasket with the replacement Carburetor before sending out to customers.

It was not much of a repair but that I was able to look at the schematics and find the right part number so there was no guessing about which part to get order was filled quickly and shipping was good
