Spark plug

the one that came with the engine should work fine. Some people like champion or nkg spark plugs. I prefer the cheap spark plugs these engines came with until they bite the dust.
These engines can eat spark plugs or are more prone to fowl the spark plug. I modify the stock plugs and the champion spark plugs and on this forum somewhere
I show how to do the changes but you will need to look on my 2 stroke sticky as I don't know just where it is.
One thing to do to your spark plug is gap it properly I use 0.017 to 0.020 gap if you have the china manual they suggest around 0.028 or more. It takes less energy to fire a close gap than a large gap and these engines don't have a real powerful ignition system to start with.
Using the newer syn 2 stroke oils will also make the spark plug lees likely to fowl along with running the fuel mix at 32 to1 or 40 to 1. The 16 to 1 is very oil rich and will fowl the plug but for break in running an oil rich mixture won't hurt anything.

Anything in the NGK B5,6,7HS range works well, same for NGK BP5,6,7HS....Iridium plugs are expensive but seem to do quite well in 2 strokes.
