Damaged or broken rings or a damaged bore are the most likely
You should be able to tell by removing the exhaust & looking into the engine while turning it over slowly

Usually, a leaking carb is because either the float is set too high, or there is some crud stuck between the float's needle valve and it's seat.
Either one will not allow the float/needle valve to shut off the flow of gas when the float bowl get's full.
no compression has the spark plug come loose, could be bust piston, rings or valves, right googled it, its a 2 stroke no valves, moving on, your have to remove the head and barrell to see whats gone, the piston or the rings. its probably the rings. its not as hard as it sounds on a 2 stroke so even a novice could do it.
Ok, a two stroke engine basicly needs 3 things to run: fuel, compression and ignition.
First, check that the fuelline, fuelfilter, or fueltap is not blocked. If the fuelflow is alright, check that the compression is fine. try kicking the kickstarter a few time: the should be a certain resistance.If the compression is wrong try changing the headgasket. If it is alright, check the ignition. This is done by taking the sparkplug out at placing it on the frame, when you kick the kickstarter a spark should jump from the sparkplug to the frame.
But my guess would be that you have a partly blocked fuelsystem.
kick it over till you feel the compression. Pull d comp lever and kick it maybee a quarter or eighth kick. just enough to get past top dead center on compression stroke. Then kick like you going to start it.
That lever is a compression release and pulling it will make kick stating an excersie routine. Kick start without the pulling the lever. See how that works. good luck.
I had the same problem, and i was that the shaft that the kick start was attached to had sezied on to the idler gear in side the engine. all i did was drain the oil, remove the cover and replace the shaft and idler gear.
It has been years since I have had a bike with a kick start, but I don't ever remember any play. Are you sure its not just easy to move untill you get to the compression stroke?
