I have had dad rebuild my weber 32/36, because you all said it was easy, so dad said he would do it. I bought a rebuild kit from Gabreile, and a power valve from Pierce Manifolds. When he rebuild the carb and reassembled the carb to the car, the car wont start. He said that there is gas running down the block. The car wont start and there isnt any gas getting into the one port. He thought that this was a bad jet so he replaced the jet and it still dont work. He also dumped gas into the dry port to see if anything would work and it didnt. I have rebuilt the entire engine and have replaced all the gaskets. Dad said that this normally happens when the fuel pump is bad but this is a new pump. I cant figure it out. If there are any answers I cant answer out here I will ask him and have a response.

When you think its the carb, check the ignition!

Gas running down which side of the block? Find it and stop it before you cook an opel. Carefully disconnect the hot lead to the coil (both of them) and have someone crank the engine while you hunt for the leak.

After you stop that, if it still wont run:

Make certain that the plugs are getting spark, and then unhook the fuel inlet line from the carb, put it in a coffee can and crank the engine to see if gas is getting to the carb at all.

Only one barrel in the carb will show fuel at low speed. The secondary opens only when the pedal is pushed pretty far down. When someone steps on the gas you should see a squirt of fuel in the primary bore.

Good Luck!

where is the gas coming from thats running down the block?only place i can think of is the accelerator pump and if so it probly just neesd the diaphram changing and the screws nipped up
it could be a blancing cap missed from one of the jetson the side but that would be very obvious

 

[weatherman]

The gas is running out from between the block and the intake. The intake gasket is brand new. There is also spark getting everywhere, so I know it isnt ignition. No parts are missing from the carb that I know of, the car didn't run well before so I dont know what the problem is now. I cant understand why the gas is running out of the car like it is. I know that the gasket it sealed well. Could it be a bad intake? I have another one should I have him switch them?

 

[T-6 driver]

I know that it sux to pull the carb, but make sure that the carb is not leaking the gas from under the float bowl, or around it somewhere. That doesn't seen right for gas to be seeping out of the intake gasket, but who knows

 

[oldopelguy]

uh, bad news

If gas can get out the gasket between the manifold and head than air can certainly get in, which would be a huge vacuum leak that would make the car run very poorly if at all. That size vacuum leak could easily lead to an overly lean condition that would melt down the motor as well. You need to address that problem immediatly. Any chance at all it's fuel from the outside of the carb or the outside of the manifold running along the manifold back to the block?

Weber carbs are pretty sensitive to fuel pressure, even more than Solex carbs. If you have a new mechanical fuel pump it might be pushing out too much fuel pressure for the float to be able to stop, and require a slightly lower float setting to compensate. What float height did you use, anyway, just in case someone here knows a good starting point off-hand? With an electric fuel pump you might just have to get a fuel pressure regulator, I've had to every time I install one.

Have you checked the tightness of your intake to head bolts? maybe they are loose? it shouldnt be leaking there.

 

[weatherman]

Dad thouhgt that the gas was running out of the intake, but wasnt sure. He said he is going to try to look and see tomorrow exaclty where the gas is running out of. I hope it is that the gas is running out of the carb and not the intake. An engine melt down now wouldnt be good, alot of money down the drain. Especially when the engine has no miles on it.

 

[weatherman]

by the way I forgot to mention, most of you might know but it is a 32/36 DGV manual choke.

Hi Weatherman, First of all, as others pointed out, you do not want gas running out of anywhere wet outside the engine, for that that matter, inside the engine.

What you want is vaporized gas flowing into the intake manifold and then into the combustion chamber/cylinders. Not liquid gas, vaporized gas, that is what the carburator does, vaporize gas and mix it with air.

If you have gas running out of the intake to block area then that gasket and/or the connection is no good, as well as there is more, the carb must be dumping raw gas down the intake manifold, if it is leaking gas as you described.

Bad carb, stuck needle valve, bad float, bad something, need to get that sorted out quick!

The engine probably will not run for that it is flooded like the crazies, pull a plug, is it wet with gas?

I would say your problem lies with your carb, need to address that first and foremost!

Let us know what you find out.

Dad says that the gas is running out from between the intake and the block at the fourth cylinder. According to you guys, correct me if I am wrong, this is the carbuerator not vaporzing the gas. I have no clue what to do with this carb now, none of the local garages will look at the car at all to try to fix the carb prob. Does anyone out there have a good carb that they want to sell? I dont care what model as long as it will fit on the car and start it. I am getting spark to the plugs, so I am thinking that it should start once I get the "right" fuel going to it. Help I am starting to get irritated with it. Dont want to mess with the car too much b/c dad has bad bursitis in his shoulder and the Drs. down here think that I am battling a pinched nerve in my neck. Go see some more drs this week sometime, so the less work needed is better.

Thanks

Toby

Wouldn't this be an intake manifold gasket or a warping problem?

 

[weatherman]

Brand new gasket and the intake came off of a running car, unless the guy stiffed me and didnt give me the one that he took off of his car.

 

[BDD]

I would check that the intake manifold bolts are tight. They are hard to get to and sometimes those are the bolts that end up loose.

I would also check if there is a certain tightening order and proper torque for those bolts. I would also think that you might check that they are still snug after the engine has been heated up. The bolts will lengthen when heated.

The carb. float level could cause problems with too much gas getting into the carb. too soon. That adjustment should be checked when rebuilding a carburetor.

You can't really get the carb. base bolts tight without having the top of the carb. off for wrench clearance.

By the way, what holds on the linkage rod on one of these manual choke carbs? It's the bent, vertical brass rod that is the last link in the throttle. It's located just behind the manual choke bellcrank. Is there supposed to be a cotter pin or something there on the top end of that rod? Mine has no hole for that kind of a pin.

With the new parts you've put into it, I'd give this carb. a chance before you spend a lot on another one which could have problems of it's own.

 

[weatherman]

I will have Dad look for you. Might be a day but I will get him to do it once he takes his pain med for his arm. Might be able to have an answer around 5 o'clock or so.

 

[weatherman]

The intake was loose and dad fixed the gas leak, thanks. Now the car acts like it wants to start and almost does, but wont stay running. how does one adjust the float? could this be the prob?

thanks

Hi Weatherman, If you have a carb problem and you get too much gas to the spark plugs it will screw them up. I cant tell you exactly what it does to them but i have heard a mechanic friend of mine say that too much gas will wash the plugs,whatever that means. I have been down that road myself and the car either wont run or will barely run. When you get the carb right you may have to replace the plugs to get your car running. John.

 

[bear]

John, what happens in a case like yours is the gas actually shorts out between the center electrode and ground tang on the plug so there's no gap for the spark to jump and ignite the air/fuel mixture in the combustion chamber. Then eventually the fuel will evaporate enuff for a spark to occur in the combustion chamber but will be so overly rich in gas it carbons up the plug and it will short out the plug with a carbon buildup. HTH.

Info

Have a look at this Web address:

http://www.fordcaprilaser.co.uk/carburettor_overhaul.htm

It has a good description of a Weber rebuild and float setting. The info is for a Ford but it does describe how to do it - not sure what the float setting is for one on an Opel.
Anyone help here with an actual dimension for use on an Opel??? Please!

Try putting "Weber float" in the Search Box - quite a few good threads are shown there but you will have to do your own digging through them!
HTH

Your last work was a carb rebuild.. I would guess needle seat isn't tight or not sealing with body of inlet...maybe to high float level..or tiny piece of stuff in float needle valve... If you have liquid gas running into # 4 be careful as it will run through the cylinder and end up in the oil.
