Yz wont start
All engines need three things, fuel, spark and compression.
What I do is first be sure, be positive, I have fresh fuel, and spark plug is clean, while the plug is out, spin the engine over for 10-15 seconds to clear the cylinder. I made a nifty spark checker out of a spark plug clamped with a hose clamp to an alligator clamp from an old battery charger, or like one on jumper cables. Clamp it firmly to the engine, attach spark lead and spin the engine, see if you have a steady blue spark. That being OK, put plug back in, choke off, ignition on spray a little starter fluid directly into the carb/air cleaner, and try to start, if it starts even for just a little the problem is with your fuel system. If it does nothing your spark isn't holding up or out of time, OR somethings wrong inside, and a compression check is in order.
Give this much a try and write back with more details, and best of luck.
