Choke problem
I have read that the choke on these 351W engines can be a problem. This is the HO version with the 4 barrel carb. Does anyone know exactly what happens and how it can be fixed. I have to hold down the trottle 1/4 for at least two minutes to get the engine warm enough to drive off. If I let go the engine stalls every time.
It fires up on the first attempt every time and I verified the idle is right. Once warmed up everything is fine.

A user posted this a while back. Mine is not connected either. I wonder if this works with the choke to keep the trottle from closing when the engine is cold??? I need this solenoid also.
"1986 F-250/460 Decel throttle kicker vacumn solenoid
I am having one heck of a time finding a decel throttle kicker vacumn solenoid for my 1986 F-250/460 with a Holley 4180 4bbl carb. The solenoid is mounted on the passenger side rocker arm cover, it has a two red wires, one in for power, and a return out for the power to the vent bowl solenoids, and a white wire out (must be the ground). It also has two vacumn lines, one in and one out. The first is from the manifold vacumn and the second provides vacumn to the throttle kicker vacumn plunger mounted on the carb just below the throttle arm. The solenoid switch is activated when the a/c is turned on or upon a sudden drop in RPM's to keep the engine from dying. Most of these type solenoids are electric only and mounted right to the carb as part of the kicker assembly, but not mine. Oh no, Ford had to do something special for my truck, just my luck. Ford Parts says this part is listed as obsolete. "
