How do you fix a weed trimmer?

Answer 1

My toro weed trimmer motor revers up super high when choke is taken off, when hit the gas to trim weeds goes even higher on rpms. Have checked oil to gas mix several time thinking was wrong, good there. How do I adjust the idle lower?

Answer 2

Most two stroke engines have a gas fuel line that feeds the carburetor. My Toro gas powered trimmer had 3 separate pieces of lines. The main line that feeds the carburetor, another short one going from the carburetor to the Bulb, and a third to siphon the excess back to the fuel tank. In my case, the main line had ruptured. First thing was to disconnect the spark plug and empty the fuel tank. I captured the piece that had dropped into the fuel tank as that had the fuel filter attached to it. I then unscrewed the fuel tank (as it made it easy to work afterwards in the small space provided). I pulled out the other end of the broken line and pulled it out of the carburetor (using a long nose plier). Cutting a similar length (actually an inch longer) of the new fuel pipe, I cut on end at a slant (like a taper) and used this end to insert into the small hole going into the fuel tank. Once inside I pulled this out toward the gas cap, cut off the end and attached the fuel filter. Then I dropped it back into the tank and gave it enough line so as to sit the filter into the bottom of the tank. I attached the other end to the carburetor and re-attached the fuel tank.
