I got my 50 running it was the vavles out of adjustment, You have to take out the spark plug and turn the motor over by hand till you are on the compression stroke then there is a small mark on the motor casing mine was a small square pin molded out with a mark in middle. then on the fly wheel there was a line with tdc. then pull the two thread off caps one in front of the carb and one in front of the exhaust you will see a small adjustment rod with a 9 mm nut under both caps you should be able to move the rods a little bit if not adjust the the vavles to .002 the intake and exhaust. This should fix it.I got my 50 running it was the vavles out of adjustment, You have to take out the spark plug and turn the motor over by hand till you are on the compression stroke then there is a small mark on the motor casing mine was a small square pin molded out with a mark in middle. then on the fly wheel there was a line with tdc. then pull the two thread off caps one in front of the carb and one in front of the exhaust you will see a small adjustment rod with a 9 mm nut under both caps you should be able to move the rods a little bit if not adjust the the vavles to .002 the intake and exhaust.

I have the same problem. If I put a spot of fuel in the spark plug hole it starts first time but will not keep running after that fuel had used up (4 seconds) I'm guessing the carb isn't giving fuel to the spark plug. I've checked the fuel flow switch which is set to main tank and petrol is flowing there.
Any ideas?

i have just got a kuzma meerkat 50cc av cleaned all the carb out washed the tank cleaned all the pipes thers a spark but it still wont turn over the only time it will run is wen a pour petrol in the carb from the top into were the pin coz in the carb eny idears eny help or idears wiil be most welcome
after a year sitting idle chances are that the gas inside the carb has degraded and the carb will need cleaning also when you filled the tank did you remove any old fuel? if not the its contaminated with the old gas
give it a full service new feul clean carb clean air filter then it should start
If it sat for a year more than likely the carbs have clogged up jets and need a good clean/rebuild,(carb kit),it may have run but the fuel in it had softend the varnashed gas and clogged the jets,also would not be bad idea to remove fuel from tank,remove and clean petcock(fuel shut off) screen,that can get stopped up too.
If no fuel stabilizer was added while the bike sat for a year or so. It is most likely bad fuel with gum deposits. This can can create some problematic symptoms for you.
It is vital the bad fuel to be cleared from tank/lines and carbs. You may need the fuel system cleaned as the gum deposits can cause major headaches in the carbs and jets. If the system is not cleaned and even after you get the bike running, you could be miles away and have the fuel fowl jets/injectors, causing shut down.
Check the spark plugs carefully. Oil on the plugs may just need cleaning. Once you get the bike running the oil should burn off if the rings are still in good shape.
If it sat for two years, you probably have varnish and gum buildup in the carb. You'll need to take the bowl off the carb and clean it with carb cleaner. You'll also need to spray the cleaner around the linkages and the jets inside. Be very careful taking apart the carb so you don't lose the float needle.
Initially, confirm presence and consistency of spark on the plug ends when cranking. Thereafter check for fuel reaching inside the cylinders by cranking with sparkplugs in place but not HT wires connected. Remove the plugs and note for presence of fuel.
Perform above spark and fuel tests; postback results.
Note: Almost always, the carbs has to be pulled out for a complete cleanup. The old gasoline could have turned to varnish like substance and coated the ports, jets, passage ways and carb bowl/walls.
