RE: Lazy tach in 4kcsq
Is the rate of change lazy or does it read 400-600 rpm low? When the
ignition is off, does the needle rest at zero or below it? If it is lazy,
check all of the connections on the back of the main instrument panel, then
check the green and red wires that are attached to the ignition coil
(attached next to the battery near the firewall where the main coil wire
comes from the distributor cap) by pulling the rubber boot and checking the
two 8mm (I think) nuts. If the needle is low to begin with, pull the
instrument cluster (if you need help here, e-mail me as I haved done this
recently!) and remove the cluster from the housing. CAREFULLY, with a
finger, move the tach needle clockwise past the numbersuntil you feel
resistance. When you feel resistance, you can "move" the tach reading up.
When the tach needle rests at zero, you are spot-on calibrated.
Hope this helps you out,
