OK, Mecoa offers two (2) different adapters for Cox .049s:
911-048 MECOA plug adapter for Cox .049 / .051 & Norvel AME .049/.061 for Standard SHORT glow plugs and
911-049 MECOA plug adapter for Cox .049 / .051 & Norvel AME .049/.061 for Standard LONG glow plugs
Now ... has anyone ran the same engine, same fuel, same day, same place with each and determined any difference? (Maybe, even compared with the OEM glow head and the Doug Galbreath head w/ the Nelson plug?)
I think I've heard all the theories - are there actual results?
