    waters not in the distributor, its in the intake where the carb came off from...

    this has nothing to do with what im asking, i took the carb off, the car was not running, i had a bucket covering the intake manifold, someone removed it and it rained and water filled up in the intake manifold into the motor...

Here is what u do, remove the spark plugs and crank the engine over for about 30 seconds, the water will be shoot out the spark plug holes, then to prevent the cylinders from rusting and seizing up the pistons spray some WD40 or any type of penetrating oil into each spark plug hole and then spin the engine to distribute it around the cylinder, also spray some down the intake while you spin the engine to coat the back of the valves, button it up and cover the intake then put a brick on it, u are done the engine is saved..

The car only likes to start when the air intake on the carb is sealed. If you start the car and then remove this seal the revs shoot up and then the car stalls. Before you do anything, scribe the housing that the water goes through and the carb body so that you can put it back precisely right! When you say that you cover the carb intake, do you mean that you are covering both the primary and secondary, or just the primary? If you are covering both you could be forcing the engine to run on just the secondary. Have you tried just one, then the other?
I don't think it a matter of "too much air getting in" but 'too little fuel getting in'. Putting you hand over the intake pulls more fuel through, but when you take it off the engine runs very lean and speeds up until it simply doesn't have enough fuel coming through to keep on running.

It really sounds like the primary low-speed circuit is clogged, which means as a minimum removing the primary main jet, air corrector jet, and idle screw entirely and using compressed air to blow the circuit out. Start with blowing into the idle screw opening, otherwise you may just be pushing the clog in tighter! Check the jet sizes while you have them out. Be careful when putting the idles screw back in, if you tighten it too much you can wreck the seat--finger tight does it. Set the idle screw at 2 turns out.

If that doesn't do it, it is time to disassemble the carb again and soak it in carburettor cleaner.
------ This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Hi
you need to clean the distributor and dry all contacts inside of it.
Check inside the distributor cap for dampness. If you find moisture, get some mechanic's solvent from your friendly service station — they use it to clean car parts — or buy an aerosol can of it at an auto supply store. To evaporate any dampness inside the distributor cap, turn the cap upside down and pour or spray some solvent into it. Swish it around and pour it out. Then dry the cap as best you can with a clean, lint-free rag and replace the cap.
Use only clean solvent; even a tiny speck of dirt can foul the points. Gasoline won't do because a spark can ignite gasoline fumes and cause an explosion or a fire.
Thanks for contacting fixya.com

How did you set the float? Usually you use a drill bit of the proper size to check the float tang clearance to the needle valve.

It really depends on what you have under the hood. And how many miles it has on it, I have an 88 transam, it has 250,000 miles on it . Still will do donuts in the parking lot. everything is original. Taken care of. But it is old and tired. Rebuilding it soon. Repost with TBI,TPI , or carb..All these make a difference. besides your engine is just worn out.

1978 Pontiac Transam, wiper motor, wiper switch and transmission all work fine.. can not get the wipers to work, Where are we going wrong. There is power to all 3 sources all wires are working.


Interesting problem! Since you have power to all three, it isn't the fuse. I can't download the diagrams right now, but I think there is a wiper pulse module in the 1978 Pontiac Transam. While it mainly controls the intermitant or delay wiper mode, if it shorted out it could cause nothing to work right. You need to verify that you do have that module first.

The engine turns on but dosent hold an idle


that year car doesn't have a lot of computer control of air mixture like newer cars do so i would look for the butterfly of that carb to be letting too much air thru while idleing. If just rebuilt did the butterfly get cleaned good? Is there a build up of deposits around the ends of it? This will let air thru and cause the problem you describe. Happened to me on a 1985 Toyota. If this helps please reply cause ithelps me continue to answer questions here and good luck

I have 88 Honda Accord with a carb.that chokes itself out within 20 to thirty seconds after start up when cold or hot. Noticed that fan has not been coming on.


The carb bowl is overflowing usually caused by a bad needle and seat. The needle is attached to the float and is pushed into a rubber seat as the float level rise to stip filling the carb bowl. Yous has stopped seating so the carb is over flowing and choking out your car.
These carbs are a nightmare to disassemble and reassemble. Even as a seasoned mech I hate messing with them. Even if you take it to a shop for repair they are going to tell you that you need a rebuilt carb due to the labor cost in man hours of fixing the old one is nearly as much as getting a rebuilt carb and installing it.
Hate to be the bearer of bad news but either way the repair cost is a wash.

As for the fan not coming on.. find the round switch with two teminals coming off of it that is screwed into your radiator. Disconnect the wires from the switch, turn on the key and then short the chassis wires with a jumper and the fan motor should run. (you might have to start the engine!) But the fan should run. If it does the radiator temp switch is bad. If it doesn't run you need to check for 12VDC on one of the 2 wires. No 12VDC = fuse problem or wiring problem.

1980 F100 with a straight 6 cyl. Won't idle.


The vacuum comes from the intake manifold and ported vacuum comes from the carb above the throttle plate. You might have a leak at the carb gasket or intake manifold gasket. Spray some car cleaner or WD40 around the gaskets and vacuum lines while the engine is running and when you hear the idle speed up, you've found the leak. You will need to install the rebuilt carb first, and you should tighten any loose intake manifold bolts. Don't overtighten them. Also check the EGR valve because it could cause the engine to stall at idle. A good tune up might be needed too. I've seen some of those engines run real rough when the ignition timing was off.
