fuel solenoid

[JasonHambelton]

What does this thing do? My '72 Sedan would not idle and I took the
solenoid off and found that it does not work. Car idles fine without
it. Do I really need this? Anybody got one?

Hi Neil;
It helps shut down the engine, and while it will run fine for a while
eventually it will cause your engine to carbon up and stop running all
together.

Ummm, don't want that to happen. Does anyone have a replacement
either new or used? Thanks. Neil

Hi. if  you get a part # I can see if I have an extra one.

Some of the carbs I have, have a solenoid block off plate, it uses
the o-ring and attaches with the original screw. The solenoid is
supposed to kill the idle circuit and prevent run-on. If you kill the
engine by releasing the clutch in gear and foot brake depressed you
can keep the engine from run-on and worse than run on is what happens
if the engine bounces back - causes the chain to jump and bend the
valves next time you start it up.
Many cars I work on have had the needle cut off the solenoid, many
owners think that is their running problem, but it is usually from a
clogged idle jet which is under the black plug in the float bowl.
If your engine idles fine without the solenoid installed, then you
really do have a problem.

That is interesting, I had never left one run for any length of time to see
what would happen. The part number for a new one is
16230-551-043.
But I have opened carbs that were still running and they were missing parts,
the Collar (the fat washer that fits into the body of the carb) or the "O"
rings on the jets. Your local Motorcycle shop should have most of the "O"
rings and plugs.

So what you are saying Miles is that if you do not use the solinoid then there is a fault? I have a 600 carb that I got recon' and the solenoid was lost.. i blocked the hole as the idle would end in stalling..
now with it sealed the car will run fine...though of course there is no needle going into the cavity... Therefore I could be creating a potentail disaster????

What I am saying is if you open up a sealed passage that leads
directly into the intake manifold, your fuel/air mix will be messed
up. Either the engine will die or race. You can actually run the car
with the top off the carb and as I recall can remove the slide but
the car won't accelerate.
The needle of the solenoid retracts when ignition is on opening the
idle circuit. If the solenoid is defect the needle stays in all the
time and car runs rough or will die if the idle becomes too low. The
pin drops into a hole in the side of inner passage nearto the
butterfly. If you just block off that hole it will run fine all the
time w/o the solenoid. It was only introduced to reduce the run-on.
That solenoid is like the o-rings they put on the rear wheels - tiny
3 bolt-on axle nut caps that are I guess supposed to keep the water
out of the already sealed bearings, same on the fronts also the
stupid horse shoe spacers for the front calipers that fall out
everytime you remove the caliper which come in 2 thicknesses - like
they would really make a difference.
