I was using my TB22EC trimmer and it quit. It's the "Trimmer Plus" model and I was using it with the hedge trimmer attachment. The plastic air filter cover has been loose for a while and i noticed it had fallen off. Putting it back on, I tried to start it using the battery jumper thing. It seemed to kick a couple times and it sounded like it backfired.
It had a good spark and I figured the carburetor was the problem, which is usually the issue with these small engines. Fuel lines and filter were clear. Cleaning the carb didn't do anything so I put a new one on. Still noting. On further inspection, I noticed "something" like a string, sticking out of the side of the engine. It was the "O" ring between cylinder and crankcase. One of the two bolts holding it together was broken. In retrospect, I think the "kick and backfire" broke the bolt after I gave it a shot of ether starting spray.
Long story short, I finally got the clutch off to remove the plastic shroud, allowing me to get the broken bolt off. (didn't have to drill, etc). Just used a vice grip to grab the bolt and remove. Have new "O" ring and bolts and ready to put it back together. Holding the piston and cylinder "something" fell out. It is a round piece of metal about the size of a hearing aid battery. Didn't know what it was at first, then found that it fits in the side of the piston and covers the piston pin. However, there is only one of these. Perhaps I dropped the other side. Should there be one on each side?
Lastly, if I'm missing one and can't find it, how can I get a replacement part?
