Tune-Up Procedure
Both the primary and secondary circuits of the
ignition circuit should be checked individu-
ally. Each circuit should be carefully checked
for loose connections, damaged insulation or
corroded terminals.
As it is not practical to check distribu-
tors, replace contacts or make any other
adjustments while the unit is installed, it
should be removed from the engine and checked
on the bench. It is recommended that the unit
be periodically removed from the engine and
the following points checked.
