I don't know if anyone has ever publicly stated the size (number) of the jet can not be trusted.
Even if the jet is stamped on it or a marketer tells you it is such and such, don't trust it. I have checked main jets from several suppliers and NONE were on specification.
These are Chinese parts, made by a very low paid worker whose pay is based on production NOT accuracy. I am not bashing China, it is just a fact of business in low price goods manufactured there.
