Weak Coil?
I just read a post where someone suggested that maybe a guy's starting problem could be due to a weak coil. My truck takes 5-10 seconds to start sometimes. But when it's warm it starts immediately. I've rebuilt the carb, have a new dizzy (points), new plugs and wires. How would I know if it was the coil?

if your float isnt set right it could be going back through the needle and seat a little but more likely down through the jets. you could have worn metering rods and they will not stop the flow of fuel when closed, allowing the fuel to leak down when shut off for a long period of time.you would need to crank for a few seconds to fill the bowl back up and that would account fdor the harder start cold. warm the bowl is still full because it hasn't sat long enough to leak down so it starts right away.

Things to check..
What carb do you have on that. If it's just the stock 2100 autolite or motorcraft it dosen't have metering rods. If your having hard cold starting sounds like your choke is out of adjustment or you don't know how to start a ford, had may have a lot of miles on it.What type of choke auto-stock or auto electric? Did you check the choke butterfly after you pumped it a few time in the morning before trying to start it to see if it's closed enough?

I think I posted the problem backwards. When it's cold outside it fires right up. Runs rough for a minute while it coughs and then runs great. Idles high til it warms up and then idles perfectly. It is the stock Autolite 2100 with an auto choke and a 360 V8. It took me a while but I've finally got the choke set right. After I've driven it for a while it doesn't start right up like I think it should. I have to hold it at half pedal for 5-8 seconds until it starts. I've rebuilt the carb but one problem with it is I think it has a little wear in the carb body where the bottom linkage rod that controls airflow into the carb sticks out the body. I can feel it. Sometimes it will catch and idle a little higher than it should. If I stomp the pedal it will usually fall back to idle. There does seem to be a little leakage out of the passengers side where that same rod comes out of the carb body. I wonder if this could be the problem. I was thinking that maybe the coil just can't do it's job when it's hot.

Hmmm that sound like every old ford truck. That butterfly shaft will not do much but make it run leaner if those bushing are warn out. My old truck has been doing this samething for about 25 yrs. My x-inlaw 70 ford truck does the samething. If your float is a little high and when you trun off the engine the heat of the engine gets hotter mading the carb and the gas in it. This may be your problem . The gas maybe pouring over abit just enough to make it hard starting. Or even the gas boiling in the float blow and droping more gas down the carb flooding. Drive it enough to get it warmed up good then park it remove filter top then put a little hand mirror tiped so you can see down the carb. Then wait 15 - 20 minutes and see if any gas drips down the carb. You may have to put in a non heat transfer spacer between carb & manifold to stop it. Try other way to start it when it's warmed up.
PS My engine started better when warm with the Stock Cam. But doing a few things it got alittle hard to start when warm. Keep looking and checking stuff and you may get lucky ..my 2cents

I've already put in the heat spacer. When I rebuilt the carb I had done asomething wrong and I once pulled off the top half of the carb body after running the truck. The fuel was boiling just like water on a stove. So I went out and got the spacer.
The main reason I was posting here is that I really like how the truck fires up immediately when it's cold. It starts within a second. It just seems like it should do that all the time. Especially when it's already warm. I think the long starts is hard on the starter. I had to replace it the other day.
