Tachometer Filter For HEI ?
I installed a HEI distributor in my 71 C/20 with standard gauge package. Trying to set idle RPM , proper advance but get no signal from the Tach connection on the distributor + Connection at distributor, - black to battery ground, Nothing . So I tried another tachometer thinking first might be broken, still nothing. After some research I read you need a tachometer filter to get the proper signal. Anyone confirm this is correct ?
