    TroyBilt TB22EC String Trimmer - No Start

    Well, it finally started, and I was able to adjust the aftermarket carburetor to maintain a respectable idle and provide crisp throttle response to full throttle. I replaced the intake insulator and o-rings, and the crankcase o-ring, and the machine started. It only took a few pulls on the cord...

    TroyBilt TB22EC String Trimmer - No Start

    I appreciate the candid reply. I should know better from working in the automotive industry. I have the original carburetor, and I can clean that out and re-use. The replacement carb is aftermarket. The engine and ignition module (coil) are MTD. I will retrace my steps and see if I can get the...

    TroyBilt TB22EC String Trimmer - No Start

    Good to know. I am still getting my butt kicked by this trimmer. New engine, new carb, new coil, new spark plug, new fuel lines and filter - No start . . . Frustrating, to say the least. Replacing the carburetor insulator and o-ring style gaskets on this part and the rear crankcase cover next...

    Other than sealing out debris from the crankcase, does the rear cover o-ring (#4) provide any sealing properties that require a tight seal? Fuel delivery is created by the downward stroke of the piston, correct?

    TroyBilt TB22EC String Trimmer - No Start

    I tried putting my 2-cycle gas mix directly into the cylinder, but had no luck getting the thing to fire off. I double checked my spark and checked my spark plug gap. All good. Below are some images of the short block I removed. I compared the location of the piston in its stroke to the feel of...

    TroyBilt TB22EC String Trimmer - No Start

    Understood. I will try my current mix, directly into the cylinder and see if it wants to start. More to come . . .

    TroyBilt TB22EC String Trimmer - No Start

    I have not (yet). I will try that, once everyone finally wakes up. My new short block came with the flywheel already installed. I can't imagine it would be out of time, but who knows these days . . . What are your thoughts on the premixed cans of fuel/oil?

    TroyBilt TB22EC String Trimmer - No Start

    I have a string trimmer that had been sitting for a long time, and I thought I would try to get it running. I did the usual: cleaned the fuel tank, replace the fuel lines and filter, replace the carburetor, and fill with fresh gas/oil mix, but still no good. I pulled the engine to look at the...
