My 66 F100 truck, 300, I-6 has a Ford Auto-lite 1100 1 brl carb, that I rebuilt my self using repair kit, was installed on 2002. this carb runs quite smooth but it has tow disadvantages:
1- burn more gas than carter carb (149 miles for 3/4 of the tank)
2- hard starting when hot sometimes.
It was running perfect when I removed it. I was planning to replace Gaskets (was leaking) that was in 2007, unfortunately the mounting base broke while removing, just wasn't lucky, then I had to change it.
I put on my new spare Cater YFA, electric choke, ( seemed to be for 1984 F150), I had to enlarge the mounting holes to fit on the intake studs. It ran very nice and starts very quick hot or cold plus saves gas( 180 miles for 3/4 of tank). It has different air cleaner, I bought from eBay.
In the last three months I felt couple of hesitations then it dies last week when I was cruising, just quits like you lost an ignition spark or wire cut in the ign circuit.
I put a new repair kit on this Carter carb but no luck, it didn't start the engine. Maybe I used a wrong kit. I ordered one kit from eBay today, I might buy a used carb and keep it as a spare. There isn't much parts for this type carb around here.
Still want to know the best places to purchase Carburetor.
Thank you folks for your reply, hope to hear more advises.
Let's cover the basics, first. An engine needs fuel, air and spark to run. It has been my experience that when an engine suddenly hesitates or dies, the problem likely is electrical in nature.
Have you checked for fuel and spark? Try pouring a very small amount of gasoline directly in the carburetor and see if it will start. If it does, most likely the carburetor is not getting fuel [maybe plugged fuel filter, failing fuel pump or cracks/loose fittings in the fuel line]. Take a sparkplug out and ground it to the engine block. While holding the sparkplug wire/boot with insulated pliars, have someone try to start the engine and verify that you have a good spark.
I have done all that, there is a spark at the plug, plus I put a new coil and a new electronic ign module(Petronix).
When I put new kit on the Carter carb, and it didn't help, I rebuilt and put a new kit on another Ford carb, the truck starts and idles roughly, it quits some times. I did not drive it, I don't think it will make a mile before it stalls again.
I will tear The Carter carb once again and clean it thoroughly, air pressure clean it, then check if it needs new parts. I will post the results then.
The fact that by changing the carburetors enables the truck to start and idle roughly does point to carburetor issues, but the rough running and dying might still be caused by ignition problems. Yes, you have checked for spark, but have you checked that the ignition timing is correct? Especially since you have replaced the points with a Petronix module.
Did you install the Petronix unit before or after rebuilding the Carter carburetor?
I am having a similar problem. F150 4 speed 1986 300 electric carburator. I have been having problems with it just dying while driving down the road at all speeds. It acts as if someone turned the key off. It can be still in gear and turning the engine over but not firing. Most of the time I can push in the clutch and turn the ignition and it fires back up. Twice now it will not start back up again. The first time it took a day of messing around when it started unexpectedly. The second time it smelled flooded and started after 10 minutes. I have replaced the ignition module on the side of distributor and have checked the coil. I have spark and fuel. Any thoughts? I was told there is a pickup module in the distributor? Might that be solution?
Now since the truck is due for tune up, I replaced the plugs and wires, put new fuel filter and fuel pump, timed the engine, plus what I did before ( new coil and new carb kit for Ford Autolite 1100 Carb. new petronix ign).
The truck started quick, idled for 20 min, then I drove it in the neighborhood, everything is fine.
I drove it to work back and forth 20 miles almost, in the way back it started idling rough. stopped at my house, let it set there for tomorrow. I guess it is the carb. I need to put a new one.
