In this video, I re-assemble the carburetor and do all the static adjustments. The video was getting very long.... I edited a hour and twenty minutes down to forty some minutes.... I hope you see how a Ford Autolite 4100 is assembled and adjusted, before installing on the engine.
I will make a separate video of installing the carburetor, and adjusting the curb idle, cold fast idle, and adjusting the idle mixture screws.
I am hoping this carburetor will take care of the surging issue.

You work like a surgeon, very impressive!👍
Good evening Howard. Glad to see another video. Lots of small componets there. You are a talented man. Well worth watching your videos. Thanks. Have a great weekend !!
100% agree
Good job Howard!
Cleanest galaxie engine bay ever
In 1982 I bought a 68 Mustang that had a 4100 on it with a really rough idle ..... when I pulled the carb off to rebuild my dad looked at the bottom gasket and noticed a split in it ..... we threw a new gasket on and put the carb back on and it ran like a top !!! ...... when I sold it it had 240000 miles on it’s original engine ...... it was still running perfectly 😁
Great learning aid. I’m about to clean my 4100
Great learning experience. Amazing attention to detail.
Another great video Howard. Thanks for posting.
Great video, Howard. A lot of the basics you talked about here crosses over to all carbs. Great stuff.
Yep, there all essentially the same...
Class is in session, we are paying attention.a lot of good info thanks Howard
Nevermind about the Galaxie! Didn't know you sold it until a minute ago. I'd sure to have liked to see it in person. Ha. So nice.
Yes I sold it months ago.
@@OldCarAlley I wonder do you remember what plug wires you used? My wire boots pulled away from the terminals the last time I removed them so that they do not seat properly on the distributor. Spark jumps between the terminals giving a rough idle.
@@whitlcj1 I got the reproduction of the factory correct wires from Auto Krafters.
@@OldCarAlley Auto Krafters. Gotcha. Good stuff. Thank you.
Hello Howard, I had forgotten about the better distributer caps from Standard and Moroso. When we were kids and used to do our own tune-ups we always looked for the brass insert caps and rotors! I recall the cheaper ones that came from China (sometimes with brand names like Delco or Autolite on the box) had the aluminum and they did burn up quicker than the brass. Sorta brings back fun times when everybody pitched in to help each other do tune-ups...it was a fun time!
I ALWAYS buy the better caps and rotors. They last. The cap and rotor on the Bel Air I bet have been on the engine a good 30 or more years. I remember I had to replace the cap all those many years back, because it had cracked, causing serious engine performance issues in humid weather.
👍Good stuff, ‘H’ 👏👏👏
I've never seen my hot idle by metal spring open. I've run the car in 85* plus weather and it always looks closed. Maybe it only open a little. I was disappointed to see that Autolite and Motorcraft plugs are made in China now. So I bout a set of NOS powertip BF 42 plugs on ebay for a reasonable price. My old Autolite plugs from 1994 still looked good so I'll hang on to them as they are USA.
It seems like everything is from China now days. I got some old NOS plugs that are in the 352.
Great job on the carb...
It's no wonder they looked for another delivery system ( fuel injection )
Engines last longer with fuel injection. All that unburned fuel blowing by rings from carburetors, especially when the choke is on, causes an amazing amount of ware, and breaks the oil down. Thats why the older cars needed two or three thousand mile oil changes.... or every 3 months, because short trips really destroyed oil quality... the choke is always on a bit in short trips.
Must be cooling off. You're wearing one of your special sweaters!
Question for you. At around 2:30 you talk about the holes in the carb to spacer gasket. All of the gaskets I see available do not have those two holes. You mentioned there may be some vacuum issues without them. Do you think the holes help? Should I add it or leave alone? I see there are notches in the throttle barrels that allow air to that port. I have a ‘66 Mustang 289 with Autolite 4100. I do not have the heater hose connected to spacer plate. Thanks for posting this, I learned a lot!
Great Video, You reference a manual with Carb Specs about 8:30 in. Would you mind passing along the name and ISBN of the book? I do alot of carb work and I think this book might be helpful. Thank You sir, Keep up the good work.
What is that book you are looking at for the carburetor specifications? It looks very handy
It's the 1966 Ford shop manual.
nEAT!
You need a Snap On TM64 carb adjusting set.
I have a ton of old OEM gauge sets for carburetor set up, I bought at a auction from a closed carburetor rebuild shop... I just couldn't fine the set for the Autolite carbs. Found the set for the Rochester 4 jet thats on the Bel Air.
I notice you have a variety of auto parts stores that you shop. Is there a goto auto parts store you prefer?
The older stores, that know the old stuff. There getting super hard to find. The big chains have put most of the good old auto parts stores out of business, the the guys that knew the stuff are retiring.
I'm going to put a 4100 in a 75 Maverick with 302, the engine is original, not modified. What jet number should I put on the primary and secondary ones? The carburetor was from a '64 Mustang.
That I have no idea....
Try . 048 primary jets and .052 secondary jets. Set idle screws to 1 1/2 turns out from seated
Are there only one or two check balls? I broke my carb down and another check fell out, but i dont know where it goes?
It's been a while, so I'll have to look at an extra 4100 I have thats disassembled.
I looked at an extra Autolite 4100 I have.... The one I have only uses one check ball, but some used two. Both are used in the accelerator pump circuit. Your shop manual should show where they go, and their size. I sold the Galaxie and gave the new owner the factory Ford shop manual with the car, so I have nothing to refer to, to show you where the second one goes.
