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.
