So what is the best spark plug gap used on a 3066 spark plug. This is on a aluminum head just to clarify

Can you tell me what motor your running an NGK-CMR7H Spark Plug in, I do not remember that number being used in most common China Girl motors on motorised bikes.
Most spark plug gaps are between .025 to .028...I use the .025 gap setting myself...I still am wondering why that particular plug number your using though as I cannot remembering it being a common plug to use with these CG's

Strange plug... in China 2 strokes normal b series ngk plugs or the ngk shorties. Either way it can range from .025 to .035. Had bike that wouldn't idle unless it was .035. Best to buy a couple and test. Worth the extra 5$ and a spare everything with these bikes is always good practice.

Cool I'll get the gap gauge meter out and test them out. Now another question is why does my motor run best then it's warm out but when it's cold it runs like half speed?

Not to sound like a retared guy but how can I do that with a stock carb? It ideas just fine but when it's cold it runs like crap

So what can I do to get it to run better in the cold air. In a car the cold air is way best but for a 2 stroke is different.
