Troy Bilt TB20CS 2 Cycle Trimmer Weed Eater will not run
I figured how and what the problem was and wanted to post the result because I can see I am not the only one with the 2 cycle beast and this problem.
The trimmer will not run if you pull the throttle. For the past 2 months I have had to run it half choke just for it to operate and its only 2 years old. The gas lines were rotten at the beginning of summer so here is what I did.
- Replaced all the fuel lines and fuel stone in the tank.
- New air filter
- New spark plug
- Fresh 40:1 fuel
This DID NOT fix the issue. So I took off the carb and it was clean. I flushed with starter fluid and it still did not work. I noticed a large screw on the side of the carb. I took off the screw and the cover it held and there was a small filter that was loaded with small particles. I flushed that screen with some starting fluid and it runs like new.
To check your screen, just remove the plastic air filter / muffler cover. Remove the one large screw on the side where the throttle connects. Remove the cover it holds on and inspect.
No carb kit, no service call, use some cleaner or rubbing alcohol.
