The 70 Z's rock!

Check the carb also, on one my two 70Z's the carb was causing a issue as it needed to be tweaked. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

If the car has the a.i.r. system in it... sounds like the pump and the diverter valve need to be restored. My old '69 Z popped and crackled. Once we sent the smog unit out to Jerry MacNeish, 95% of the popping, crackling went away.

Can i just disconnect the a.i.r. to eliminate that from the crackle causer possibilities?

Try it to see if it goes away.
