Can maverick run without carb?

You must have forgot about the "How do I stop my Maverick from doing Wheelies at green lights" Thread..

 

Sorry, neither that thread nor this thread top my all time favorite thread on a car forum.

"Dual Battery the Army Way"

Batteries zip tied together, he used AC home wiring charts to pick his wire sizes (22ga solid core copper on EVERYTHING!). 15 pages of people telling him he was going to burn his Bronco down. and finally the epic picture of the engine bay and the truck in flames. That was a really funny week.

On topic though. Maybe he found the air cleaner box in the trunk, and just doesn't realize it's not actually the carburetor.

If you car doesn't have an air cleaner box on it WILL run like garbage.

 

Well Guys we have learned something! Take the carburetor off, and you will not have to buy gasoline. just think of the mileage that you will get.

 

Really ? Since when ?

 

lol.. I was wondering who'd be the first to pick on him for that one.

This ain't a 2-stroke.

 

I'm all for him getting the car AWAY from where its at right now SOMEONE from his area telling him who he could go to for a decent mechanic or he's gonna spend a ton of money for nothing cause if the guy's telling hin that about the tranny already he's in for a screwin that ain't never gonna end and a car that's not worth the money he's putting into it.the dude doesn't know cars that's for sure but he has to start somewhere I get that but dude get a book from here that shows you what your cars supposed to look like and start with the easy things to fix and one thing these people are good at is helping anybody do anything to our cars,small or complete overhaul.good luck!

 

Holy Jesus man!.. sentences.. sentences.. sentences. And maybe even throw in a paragraph or two while you're at it.

There's a lot of old guys around here(not me though).. and that's pretty tough on the old eyeballs.

 

Oh come on. Just loosening the ****ing bolt on the air cleaner drops the vacuum. If you have an already crap running car not having the air cleaner on top of the carb jacks it up.

If you want to argue this be my guest. I'm going to ignore you.

1 more point to make on the issue though. Just because many of us have different levels of understanding of how an engine works, how different engines work, and how different machines function does not mean that what 1 of us thinks is right or wrong is actually right or wrong.

If someone doesn't have the first clue, start somewhere very simple and explain it in basic terms.

I.e. not having the air cleaner on top of your carb can make it run like crap because these engines include the air cleaner box in the PRESSURIZED CRANKCASE VENT system. Therefore - removing the air cleaner box is a MASSIVE vacuum leak. In the stock configuration. Which can be tuned out.

When I first started working on older cars I had NO ONE to help me. I had never opened the hood on a car older than like 88, and that was only to put oil in. I took a class in basic automotive maintenance at a GM plant once in middle school, and I had an extensive understanding of industrial machinery, pneumatic/hydraulic system design and repair, and not much else. I did not know exact what was the carburetor and wasn't the carburetor back then either. I actually thought the air box was the carb until I got straightened out by going down to an auto swap meet and just asking questions. I actually got a guy to just tell me what everything was in his engine bay when I pointed at it. So yea, I don't care if you guys want to tear me down, but consider that maybe when I post a response I'm not just waving my **** around like some of you are.

 

holy cow.. take it easy, man! I was just teasing a bit and I wouldn't have even said anything if I figured I'd be fueling any more feuds around here.

And.. no salt being rubbed here at all.. but I won't even get into the physics involved with engine vacuum changes related to changing pressures above closed throttle carbs.

Only way I see that happening is if the air cleaner is very nearly completely closed and the result of loosening that screw actually allowed more air to be drawn into the engine.. thereby reducing the vacuum above the closed throttle bores.

Of course.. fuel mixture would be nearly unusable to keep the motor running due to emulsion tube related problems and not to mention the reduced Bernoulli effect in the venturis.

But.. anywho.. I'm no scientist designing the stuff.. I just mod it to work better is all.

And PS.. a "PRESSURIZED CRANKCASE VENT" being located in ANY airbox.. is in an area of atmospheric pressure to begin with.. so yes.. it IS a vacuum leak to begin with whether the lid is on or off. PCV valve exposure to atmospheric pressure (being on the one side of the engine and venting through it to the air cleaner on the opposite side).. creates that affect. That's why the engine idle speed changes when you plug that port. You stop the leak.

 

wow this got ugly! I'm out.sorry I said anything.

 

Trust me when I say, it is very easy to make the cab so unstable it doesn't run without the air box on... and no I don't really want to discuss how many times I rebuilt that stupid carb... which was probably the whole problem to begin with.

and to the PS... in the stock configuration using a proper air cleaner it should make a seal that creates multiple pressurized zones inside the air box. The difference is slight but there.

 

oh wait....anybody notice chany's out to.it's getting so we can't say anything on here anymore without people talking crap to eachother instead of helping the guy.now I'm out.

 

I've done and tuned many engines though the years and watched hundreds of others do similar and never seen that happen on anything short of a finicky 2 stroke engine. Even then.. idle characteristics change very little and leaning occurs at higher airflow/high-rpm.

And you may want to check your knowledge base on that "pressurized zones" thing. It's only called a closed system because the air cleaner takes over the PCV valves duty when the engine reaches 0 PSI vacuum(unless the carb is severely undersized for the camshaft head combo.. WOT = atmospheric pressure). Most air cleaners pressure reading is going to remain at atmospheric whether the engine is at idle or WOT.

In other words.. a high performance air cleaner only lets more air flow(potentially increases power) as result of less media restriction and smoothing turbulent airflow.. NOT because it changes the pressure conditions in the environment that it's located. Any sufficiently sized air cleaner is always going maintain 0 PSI unless there is very severe restriction somewhere along the air entry path.

 

This thread went off the rails fast. And any time you try and "dumb" down to the newbie level the sharks come out.

 

Just answer me 1 question. Would you drive your car down the freeway without an air cleaner on it given the choice.

Specifically, would you be willing to drive a car that was so nasty in the engine bay you couldn't tell if it had a carb on it or not, without the air cleaner on.

Also, I don't think I need to check my knowledge of anything to do with vacuum systems. I've done way more complicated things with vacuum than a car is doing with it. Essentially you do not NEED an air box on the carb at all. I'm not disagreeing with you on that point in any way.
