Very usefull advice, well done
Get a multi gov pro jetfixrguy and use the GV-1 for a paper weight
Nothing wrong with the gv-1.
From the manual
Mixture rate setting MGx/MDx
Each point of the mixture curve can be set. When the "Gov" mode is set with the "mixture servo operation mode" function, "MGx" is displayed and when the "Dir" mode is set with the "mixture servo operation mode" function,
"MDx" is displayed at each point. ("x"shows the number of characters of each
point.) Nine points can be set.
