Troybuilt TB146 EC tiller - four stroke
1.) Removed the 4 - 5 top cover screws
2.) Removed the air breather cover, filter and filter grate, and assembly. See the spacers in the housing for the long bolts put them back, a big help to have.
3.) Removed the carburetor.
4.) Disconnected the throttle connection from the carburetor.
5.) Lift and discounted the throttle cable securement from the body of the motor, use two standard screwdrivers to push in on both sides of the holder, it just lifts off and out of the way.
6.) Remove the carburetor gasket, big cardboard piece. Remember to tuck in under the plastic housing when reinstalling
7.) Remove and reinstall the spark plug if needed, did they come pre-set, the carb too.
8.) Re-install in reverse.
9.) Change the oil while you are there. Do not overfill or it will run out of the air breather assembly.
10.) The power bit starter is great, all small engines should have one of these. A standard square bit, I bet would work too.

Trimmer would not stay running anytime I would increase the throttle. I had previously replaced the fuel line, filter and fuel and that didn\'t resolve the problem.

Tools:
Pliers, Screw drivers
Remove the clutch cover. Then remove the spark plug and insert a length of rope into the cylinder, leaving a few inches out. Then pull on the starter rope until the piston comes in contact with the rope and stops the engine from turning. Then using a torx T-20 (As I remember it might be a T-25) remove the clutch drum. Then with safety gla sses on, strike an edge of the clutch with a hammer and screwdriver until it is loose, once usually does it. Then remove the old starter housing assembly by removing the screws that secure it. An install the new one. Replace the clutch assembly and clutch cover in reverse order of tear down. Remove the rope from the cylinder, and install the new spark plug gapped at 0.025 I also replaced the o-ring between the cylinder and rocker cover.
