Orifice Spark Advance Control connections
« on: October 31, 2020 - 08:30:15 AM »
I have a 1973 Challenger with California emissions.  Where do the hoses connect to for the  Orifice Spark Advance Control valve?  Thanks.

I figured out where they go. ;D One to the carb and the other to the distributor. Now if only I could post pics on this forum.  ::)

Do you have a FSM? I would think it would show you something there.

05 Hemi Durango, 01 Ram 4x4, 14 Ram 2500 4X4, 10 PCP Challenger 6 spd RT, 01 Viper GTS ACR, 52 B3B w/330 Desoto Hemi, 70 Hemi RR (under const)
Past Mopars
9 x Challengers. AAR Cuda, 4 RR, 2 GTX, 4 Chargers, etc... (too many to list)

I do but it doesn't show exactly where they connect on the carb or how the lines are routed.

Gotcha, I always hate saying "check the FSM" as I figure most have but many times that is not the case and when I do not have a good answer, I am left with suggesting the FSM.

Sounds like what you need is a survivor or a very well done resto to see what goes where. Unfortunately all I have is hot rods so I cannot help with this, have you tried some of the other forums?
