its got a great strong spark, great compression, very spotless carb, great reeds. ran, recently then died out. wont start again. ive change spark plug, even tried running gas straight to the intake manifold to the cylinder. the plug comes out wet but doesnt start engine. crankcase oil level is low. randomly on a rare occasion the engine will give a SMALL backfire which sounds more like the engine breathing out more powerfully then when kicked as if it almost wants to start. another detail is the clutch is currently not working and acting like its always depressed... i doubt that changes anything. form the details given..... any ideas??? thanks!
air cleaner is brand new. gas isn't extremely new but i can dump on the ground and light with a match so i know its flammable
