2 Cycle Trimmer Only Runs on Choke | Won't start - How to Diagnose & Fix

How to Diagnose & Fix a 2 Cycle Trimmer that Only Runs on Choke. You need to see this!
This trimmer is almost brand new and the landscaping company ruined the engine by running straight gas (no 2 cycle oil mix) in the engine. They had to replace the engine and after doing that it would only run on choke. They couldn't figure out what the problem was and asked me to take a look at it. I found 2 common problems for the reason it would only run on choke.
If you have a 2 cycle engine that will only run with the choke on, I think this video will help you diagnose and repair that problem.
