Believe it or not that engine is a chinese copy of a Mitsubishi design that is just like the 43cc version but differs from the 47cc version and it has no reeds, check here for a break down of the engine: http://elescooterparts.com/scooters/Schematics/49CCexpV.html

-I just got a good laugh from you saying your mini ninja had a weed eater motor LOL
-That engine doesn't have a "reed valve" in the conventual sense as a motorcycle has a reed block with valves.
-Where the carb bolts to the engine, there is a metal flap that blocks the carb's ventury.
-When the piston is on the intake stroke, the vacuum created pulls the flap open like a doggie door. Just make sure that the flap seals when in the closed position (and make sure it's in the right direction - it opens in, towards the engine).
-The most common mystery problems with this kind of motor is -
Carb jets are clogged
Fouled spark plug
Bad gas
-Drain the gas tank dry - get some brand new fresh gas from a gas station (don't use what you have lying around your garage) - and mix up a new batch of premix.
-Change the spark plug
-Check the carb
-With the spark plug out and no gas in the tank, crank the motor over to blow any junk out of the cylinder.
-Install the plug, add gas and fire away.
Thanks for telling us what type of motor you have. See, it makes a difference.

Hey,
If you are searching for Mini Ninjas you can download it for free here: http://bit.ly/Y2S2sQ
no surveys, no scams, just the full game!
The plot of Mini Ninjas is also very interesting. You must play the role of Hiro, a small Ninja who must train and fight against thousands of enemies to frustrate the evil plans of the leader of the Samurai.

the reed valve is between the head and the carb.

Another problem usually blamed on the carb are bad crankshaft seals,allowing air to enter at the crankshaft.Hard or no start,if running will never run right and will run lean.
