You need to check for vacuum leaks around the intake manifold.
just use a little carb cleaner and spray around the intake while some one is trying to keep it running. if it changes the idle that is where your leak is
unless your plugs were black then that is a over fuel problem and your carb float is sticking.
good luck

Cleaned out carburator on a F100 straight 6. Now


I would suspect there is dirt in the idle system, did you blow the jets and passages out with compressed air.

Ned to now wat the firing order for dist cop shood be for a 1987 ford f100 pick-up truck 300sixcylender stick shift model#333


The F100 ended in 1983, so there is some confusion on your 1987 Ford F100. The F150 started in 1983 and was available in 1987, but not the F100. You have this listed under the 1981 Ford F100 category.
The 300 CID = 4.9L In-Line (Straight) 6-Cylinder.
In order to best answer your question I have included both the 1981 F100 4.9L and 1987 F150 4.9L below. The only difference is with the Distributor Cap Configuration and Connections.

For the 1981 F100 300cid=4.9L:
Firing order:
1-5-3-6-2-4
Cylinders:
(back)
...6
...5
...4
...3
...2
...1
(front)
Distributor:
...(back)
.........4..[.]-clip
2
...................1
6
................5
[.]....3

For the 1987 F150 300cid=4.9L:
Firing Order:
1-5-3-6-2-4
Cylinders:
(back)
..6
..5
..4
..3

Distributor:
.......(back)

1980 F100 with a straight 6 cyl. Won't idle.


The vacuum comes from the intake manifold and ported vacuum comes from the carb above the throttle plate. You might have a leak at the carb gasket or intake manifold gasket. Spray some car cleaner or WD40 around the gaskets and vacuum lines while the engine is running and when you hear the idle speed up, you've found the leak. You will need to install the rebuilt carb first, and you should tighten any loose intake manifold bolts. Don't overtighten them. Also check the EGR valve because it could cause the engine to stall at idle. A good tune up might be needed too. I've seen some of those engines run real rough when the ignition timing was off.

1980 ford f100 choke no voltage


I have somewhat of the same problem but not really. I would check the fuse but you have probably done that. I would run new medium grade wire from powerpoint ( 12V source ) that is hooked up to your ignition. Then run to your choke wire. you can also do a manual set of the choke to get it started. My choke doesn't work at all and needs to be replaced. Having the same starting problem though.
