My instructions on how to adjust this parameter are not clear. Default is 2 degrees advanced, and it "is adjustable from zero additional degrees advance to, to 4 degrees additional."

But the instructions don't say how to adjust it from 2 to 6 degrees advanced nor does it say in what increments it is adjustable.

Hate to bother Bob with a direct note...anybody already know?

Thanks, Bob
From Bob...........

low gear spark = .25 degree per count in that cell. "8" = 2 degrees.
"15" = 4 degrees. "0" = no additional spark advance in low gear.

Thanks...that sure isn't the way I understood the instruction wording...but it makes sense.
