Can you explain to me in layman’s terms what’s wrong with itThought I was going crazy too, that carb!

How would the carburetor Be able to start the car and keep the car on if it’s not on right?I wonder if the jetting is even close? What about the power valve?
Your fuel injected cars have a sensor in the exhaust. That sends a signal to the fuel injectors to either add more air or add more fuel. That keeps it running pretty much perfectly at all times that's the nice thing about fuel injection. The carburetor generally has a primary setting and a secondary setting. And there set. They can be set a little off and still run relatively well.How would the carburetor Be able to start the car and keep the car on if it’s not on right?
Total agreement Jpar. One thing at a time. It current starts and idles, get the temp issue covered first.
Appreciate that detailed explanation and 100% agree that I want to fix this issue before moving on to the carburetor problem but do appreciate yellow rose pointing that out I would’ve never noticed if he didn’tYour fuel injected cars have a sensor in the exhaust.

So the where the carburetor works is like your toilet. You know how that little float inside the back of the toilet goes down when you flush it and it pulls water in until the float goes all the way to the top. That's how your carburetor works. It has a float in it or a couple floats that keep the fuel to a certain level in the float bowls. Then as air is drawn through by the Pistons going down and drawing are it also draws a little amount of fuel through a jet. Know if you put a bigger jet in it will draw more fuel and make a richer mixture.. and the opposite is true with a smaller jet. The idea is to get the perfect setting for the car that you're putting it on. of course I'm saying it this way because you're asking for layman terms and I want you to have an idea of how things work...
If it runs too lean as in not enough fuel in too much air it can run very hot. kind of like a blowtorch when you turn on the gas it just has a flame but when you add oxygen it turns into something that can cut steel...
It sounds like you started here with just a little bit of a heat Spike from a new cam break in. Careful this form can take you into untold in uncharted territories and have you more confused then you need to be. Now I'm not doubting the guys that are saying your carburetor is backwards or something like that but it seems like he probably just put it back on the way it came off? Let's just tackle one thing at a time here..
I am going to buy that radiator cleaning kit it really helps when bleeding the radiator and about the fan you have any brands you’d recommend cause that and the radiator is something I was planning on upgradingYou could always go get a radiator cleaning kit with the"T" that bolts into the heater lines and hooks up to the garden hose, has the yellow funnel thingy that hooks into the radiator cap location, and speed the water out of it.
Also I suspect your electric fans are not cutting it.
Recently I measured the air speed my stock mechanical 7 blade fan makes at about 2000 rpm and it was about 45 to 50 MPH
Haven’t tried that I wasn’t trying to take the car on the highway when it was overheatingHave you tried cruising at higher speeds, 45-50. See if it cools with more air flow and/or levels off?
You remember what cfm was that electric fan? Cause I ordered a cold case Aluminum radiator And I’m about to order the fan shroud with it which is a single 16inch electric fan rated at 2500 cfmHave those fans prove them self in the past? Like keeping a previous motor well into a happy temperature range? I had dual 12-inch fans that really didn't cut the mustard very well and I ended up putting one very good 16-inch fan in and now all is well...
I will try this today and get back to youDid you ever shoot and get temps from top and bottom rad outlets when "hot" ?
It's gotta lose 40* + !
As I recall when you look under fans and under 16 inch fans and puller fans for sure not pusher you want a puller fan but a lot of them are reversible. It was like the first one on the summit catalog or on Summit website under fans and I think it was like $140. You don't want to buy a cheap one because you get what you pay for. Definitely buy for $35 I think it is a adjustable thermostat and don't buy the cheap replacement one because that doesn't give you the bracket. And put it on a relay...I will try this today and get back to you
Did you just get the fan instead of the fan with a fan shroud because the shroud didn’t fit? Cause I only have about 7 inches of space between the radiator support to the water pump pulley and since the cold case radiator I ordered is 3 inches thick and the fan shroud they sell is 6 inches it won’t be able to fitAs I recall when you look under fans and under 16 inch fans and puller fans for sure not pusher you want a puller fan but a lot of them are reversible.

You can also look at fans by their thickness. I usually use Summit for a multitude of reasons.. I like electric pans and I don't like Factory fans. It was a personal preference.. I don't like what I call the whirling blade of death...Did you just get the fan instead of the fan with a fan shroud because the shroud didn’t fit?

I usually use summit so I’ll check, any other way I can keep put the fan on the radiator without using zip ties?You can also look at fans by their thickness.

Well I'm sure you could make some kind of bracket if you wanted to but the standard is to use not technically zip ties but they poke through the radiator and like a zip tie kind of zip on...I usually use summit so I’ll check, any other way I can keep put the fan on the radiator without using zip ties?
Would that come with fan or would I have to get that separately?They look like this... put a washer on each side and poke it through the radiator and through the fan hold down a little foam piece between them...

It should say in the description with Summit... But if worst case scenario came you can get them at the parts store for about 7 bucks or order them...Would that come with fan or would I have to get that separately?
