Trimmer Would Not Start

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.
