Thats what I was getting at, bring idle speed down & make sure motor is not running hot.

[FrankieT/A]

Idle speed is too high in park or neutral....

[kenzoil]

Keith, it's an automatic, temp is 180. To my understanding , by turning the idle speed screw counterclockwise, that will generally lower idle speed. Also, by turning the mixture screws counterclockwise , that will normally make the fuel mixture more rich, correct? I think it's back to the drawer board for the 10th time, to try to get this right.
I made the adjustments previously, and the car seem to run pretty good around town and on the highway, with no pinging etc. I just can't get the damm thing to turn off.
Cleaned the combustion chamber, etc with no results. The idle might be too high, but I got it to run well, until I wanted to shut if off.

[mechanickeith]

You are correct on idle & fuel mix. I leave mine in gear when shutting it down. I give the throttle a little blip while in gear & then turn it off as idle is coming down. may not work with yours

[kenzoil]

so am I right in my assumptions, counterclockwise out on idle screw in back of carb to slow idle speed, and counterclockwise out on fuel mixture screws to richen up mixture ?

Yes,,,Note,,,mix screw only changes idle fuel air mix,,for a change in the cruise fuel air mix, a change of the internal jet is needed.

[FrankieT/A]

Mixture screws out(counterclockwise) to lean. Idle stop screw out to lower idle RPM

[kenzoil]

Frankie, trying not to be smart, but counterclockwise out will richen up mixture not lean,according to Keith, etc??

So I purchased a Carter in line pump, drawing 5 amps tops. I have 12 guage wire, fuse holder, toggle switch (good idea). Do I really need a relay setup , when the pump is only pulling 5 amps, and I am using heavy guage wire?

That should be fine! put in a 10 amp fuse & run it!! No need for a relay with only 5 amp draw. 12 gage wire should be fine. What is the PSI rating on the pump??

[kenzoil]

Keith, pump is rated 4 to 5.5 psi. I thought that would be a good match.

As one who has recently been upside down in a vehicle, I'd again like to recommend a roll-over cut off switch.

Good idea Bill!! Sorry to hear about your truck!!! Ken,,,You can get one of these at just about any parts yard. Most newer Fords have them & they are usually mounted behind the passengers front kick panel. Has a couple of wires going to it with a red reset button. This will trip & shut off the fuel pump if you are in an accident or a rollover. If it trips from bumping a parking lot pole or something, you just push the red button to reset it. 4 to 5.5 should be fine.

Keith, I followed your directions and installed my inline fuel pump. As far as a cut off switch, I bought a used inertia switch , from a 95 ford mustang product, Appears to have 2 leads and a large red reset button. . I assume you just splice it into the positive feed wire, and mount it level under the dash, correct? My understanding is that it will kill the fuel pump flow if I hit something, but how about a roll over ?

[mechanickeith]

Yes, will work also for a roll over. The switch has a heavy pendulum that hangs down. Any sudden hard movement makes the pendulum move & cuts off the power. Just mount it level with the red button straight up.

[kenzoil]

By button straight up, do you mean to mount the switch so the button is on top of switch, not looking out facing you, correct?

[mechanickeith]

Pointing up, away from the floor board. Button on top of switch.

[kenzoil]

Keith , as usual thanks for the help.

Use the better octane. Non oxy if posible. Use a can of " sea foam " Octane booster helps too. I still get it even with all this stuff. John
