Ford 302 Carb overflowing

I have a Ford 302 that someone stuck in a jeep I have purchased. The carb didn't have a tag on it for a rebuild kit so we matched one up by gaskets, etc. When the engine is idling it seems like the float continues to let more gas in and it overflows out of the top ports on the carb and then is sucked into the butterly. What causes this? Are the ports supposed to be sealed off. I really shouldn't say they are ports, they are more like a couple of stacks off of the top of the carb above the float area.

Either you have the float level set too high or the needle valve is either defective or has something holding it open. To clear it you can sometimes remove the fuel line and put it into a gallon container and run it with the line off till the carb runs out of fuel, then re-connect the line. If that does not work open the carb up and check what I mentioned. If it's got a Holley 4bbl on it some can be adjusted externally.

How to rebuild a 1987 plymouth gran fury 2 barrel carburetor

First, you will need to get a rebuild kit for it. This contains gaskets and other bits that wear and need replacing on occasion. There will be a number on a tag or the carb body that the parts store will need to get the right kit. There's no point in trying to reuse the old gaskets, if you are going to try that, then don't waste your time rebuilding.

The kit will contain a sheet of paper whjich will give you an exploded diagram of all the parts in your carburator and where they belong. there will also be information on various settings for idle, choke, etc. Don't lose these sheets.

When you start to disassemble the carb, keep the old gaskets to compare with new ones. When you remove the idle screws, turn them in until they stop. Be gentle when you do this and count the number of turns. Write that number down, so when you put it back together you know where the idle setting is supposed to be. There will be extra gaskets in the kit and they will all be different. You must replace with exactly the same as what you took off. Also pay very close attention the how the choke linkage comes apart. It will go together more than 1 way so you can get it wrong. This will make the car act up or maybe not even start.

Soak the carb in a good quality cleaner and make sure everything is clean and all the lines are open before you start to reassemble it.Use your diagrams to make sure you put everthing back where it belongs, replacing with new parts when possible. Be very careful with the float measurement, it must be exact, close won't work.

This is going to take you several hours, so don't be in a rush.

1969 ford mustang revs up on start then immediately dies.

Sounds like carburetor problems. Does the choke plate open enough to keep engine running? Or the fuel level in the carburetor may be too low-adjust floats for that. Check idle speed settings -idle speed screw. Idle mixture setting-the idle mixture needle.
If still no help, buy a carburetor rebuild kit for it-not expensive, will have all new gaskets and the parts that normally wear in the carb. Instruction sheet and a numbered dismantling sequence will be included in the kit. If you have never taken a carb. apart, let someone who has do the rebuild, an awful lot of tiny parts to keep track of, and you cannot let mix-ups occur. One wrong jet in the wrong place, and you will have to do it over. One check ball that wasn't placed, and you have to do it over. Mechanics are glad that carburetor days are over-fuel injection is more reliable, with about a hundred fewer parts to check on.

Engine wont start it backfires through the carb

Make sure the timing is correct. Backfiring is often caused by an engine out of time.
Good idea on the carb rebuild. It may be letting too much gas in.

What could be the problem with the carb if going through way to much gas? 2 barrel carb &manual choke? F150 doesn't want to run very good when cold. Truck just guzzels the gas after started. Got a 302...

Possible things to be considered: Float level too high, needle has a bad seat and won't shut off, vacuum leak (either internal or base gasket), choke not properly adjusted.

My money would go on a carb. rebuild kit (but only if you feel comfortable attempting it) it's not all that difficult, but you MUST be (1) an absolute nut about cleaning it all very well, and (2) the various gaps, clearances, adjustments, must be made with excruciating precision.

This will be a lot cheaper than a rebuilt carb., and you'll get the satisfaction of doing it yourself.

While you're at it do a general tune up.....plugs, points condenser, wires , air filter, PCV, etc.

Truck starts, but has a hard time staying running. smells like gas under hood and smokes. could my carburetor be bad?

I wouldn't say that the carburator is bad, but it may have some defective components in it, like a sticking float or leaking gasket. Can you see any fuel leaking in or around the carb? You can purchase a carburator rebuild kit at most autoparts stores. You must have the right number for the carb. There is usually a metal tag attached under one of the bolts that hold the carb to the throttle body that will have the number on it and sometimes it is stamped on the carburator body. Before you dig into the carburator, however, check for more mundane causes, like a faulty or fouled spark plug. Hope this helped and best wishes.

84 s10 carb

Any auto parts store can get the kit for you. The carb should have a metal service tag attached to one of the screws on top or side. You'll need the numbers on this tag to get the correct carb kit. If no tag is found then look for numbers either stamped or cast into carb, probably on bowl or on top.

I have a 1988 ford bronco it is ideling low when u give it gas and let off trucks idle goes all the way down and shuts off start it back up does same thing it kinda runs rough to

I am assuming it is a carburated engine. Sounds like the accelerator pump is not pushing the extra fuel when required as the accelerator is depressed. Time to rebuild the carb. The kit will contain a new accelerator pump. Look for a tag on top of the card with numbers and letters on it. It will let the parts house you go to know what specific carb is on the vehicle so you can get the correct rebuild kit. Good luck.

1988 jeep wrangler carb trouble

Ok... If you have any experience with carbs, you can get a rebuild kit. The most important part of any rebuild is to clean out obstructions in the passageways. Most times this can be done by using carb cleaner and spraying compressed air through them.Most times, just spraying cleaner into carb while installed is a waste of time as debris usually consists mainly of fine rust particles from inside the fuel tank, which will remain in the fuel bowl unless physically removed. If you can't do this, next best option is to search local junkyards for a similar unit. When replacing, cut the fuel line in a convenient place ahead of the carb inlet and put an aftermarket filter in the line, to prevent debris from re-entering and causing further problems. Most carbs have the adjustments blocked off. before using, it is wise to have someone who knows how to remove those plugs, do this for you so you can adjust it after installed.
Good luck

1985 truck cuting out when excellerating.

Maybe this would be a good time to rebuild that carburator. New seals, springs, gaskets, maybe the high speed jets are clogged. What year and motor do you have? 302 - 351 - 300?
You should be able to pick up a rebuild kit fairly cheap these days.
