Again, there is no such thing as a factory needle setting. Glow engines don't have them and nobody ever asks glow engine manufacturers for "factory settings" What on God's Green Earth leads anyone to believe that gassers have them?
To me a "factory setting" is just that, a SAFE starting point. The engine is not meant to run perfect on these settings. Way too many variables for one needle setting for all.......
