Frustrating 2 cycle trimmers

Hello; I have been trying to get two Ryobi 2 cycle engines to start and run but still after disassembling, cleaning, replace gaskets and I replaced the carbs as well, they are still laughing at me. Dang things I am about ready to toss them but one engine is on a small tiller and if it would run it would come in handy. Does anyone have any suggestions? I am open for all suggestions. It may take me a while to try them because I have a lot on my plate right now but, HELP!

    Do you know what models the Ryobis are? What exactly are they doing, not starting, etc?

    All I can give you is the engine size: 31cc, 15 inch, and a tag with these numbers: 40a6987, 99, 904-7369287. That is all I see to give you. Sometimes if my arm holds out I can start it for about 5 seconds then it quits and that will be all I can get it to do. I have put a new plug in it, replaced the carb all new gaskets I dont know what to do. Oh, Sometimes after trying to start it gas will start dripping from the carb. I can work on 4 cycle engines and make them run but 2 cycle ? FRUSTRATING!!!

    Did you replace fuel lines and fuel filter? If I am looking at the right model, looks like a spark arrestor screen behind muffler. Have to take muffler off, make sure the screen is clean. While muffler is off check condition of the piston and cylinder.

    I agree the muffler screen may be plugged.
    I also think this is a very old unit.

    check for spark! If it starts and runs with starting fluid, its not getting fuel. And like others have suggested, remove the muffler and check the exhaust port and spark arrestor.
