Spark Control Valve

[Anonymous]

The Spark Control Valve (SCV)...Does anyone know what this does for the 1100 carburetor.

I have one on my 1100 and am not sure if the car needs it as it is a manual transmission. Can it simply be removed and the hole plugged or is there some magic to it's function????

What spark is it controlling?

Thanks,
Steve-O

That carb may be for a later year/model car because I don't believe that Ford used the SCV on a 1966. This was an emmisions control device. There were various configurations through the years and in order to work correctly you would need the EXACT distributor, temperature sensors, blah, blah, blah :roll: I would leave it unhooked and be happy

Isn't it part of the Load-o-Matic system? Or am I confusing it with something else?

Steve-o, if you have a loadamtic distributor you need the spark control valve. See jack collins post above your post for a very through description. If you have a centrifigul advance distributor you need manifold vacuum only, or ported vacuum. You don't want venturi vacuum going to the vacuum advance at full throttle. You can remove the spark control valve & plug the venturi vacuum passage. Then put the spark control valve back in & you will have ported vacuum advance when the throttle is cracked. Good luck william

I've got a 66 convertible but it has a 1968 200 cid engine with a distributor that has centrifugal advance and vadcuum advance.
Actually the distributor has two vacuum connections, one I suspect for advance and one for retard. I use the advance side only.

So would I need the SCV with this dizzy and an autolite 1100 on my manual??

Ooops I really should look in the book BEFORE posting, not after. I was thinking of the PVS (Ported Vacuum Switch). This was used in conjunction with a coolant temperature sensor, etc. There were various other inputs, some dependant on vehicle speed or gear selection. Boggles the mind. I wonder if there are any cars from the early 70's with all that stuff fully functional today?
