MGB: HELP !! MONEY/PARTS REWARDED !!

OK, first of if someone give me the info to acomplish this problem and fix the problem, { info or someone comes out and fixes it on there own, i will reward 35$+ANY 3 PARTS OF THE 79 mg midget im parting out !! ANY except engine and tranny.


OK: now the problme< , i have a 76 midget with the spitfire 1500 engine, i had bought it as a 20year old barn find and fixed lots of parts and reaplaced lines and etc, anywase we had problems starting it and thought mabey its the carb { ZENITH STROMBERG} or mabey its the fuel pump, so did a re-build kit and still problem,

So i had bought a 1979 mdget same engine, for parts as mine was missing some and this was 100% complete just BAD BAD BODY, so parts car, and i had managed to start it on first spin !! ran around the yard runs PERFECT !! so i took the carburator and FUEL PUMP off of it, and put it in my 1976 midget that had the problems, i put it in , and same dam problem !!!!


i put the old carb from the 76 into the 79 that was running and it runs PERFECT !!! so both carb work on my 79 parts car BUT NONE on the 76 car !!


NOW THE PROBLEM IS: when i turn on the fuel pump{ IGNITION} it just POOOOURS gas out of the carburator going out the filter and also into the intake manifold, and it happend on both carbs from both cars but ONLY ON THE 76, but DIDNT HAPPEN on the 79 PARTS CAR !!,


so my question what could it be ? if u help in any way i keep my word and i will reward u , or if u live north illinois or south wisconsin come out !! ill give u food/water LOL , im in rockford,il ANY HELP WILL BE GREAT !!! thankyou so so much.

TK,
You could put the 79 engine in the 76. No need for a reward. :)

You said both carbs, are you running the twin HS4 Euro set up on the 1500, or by both carb did you mean the two different single carb assemblies? I may sound like a broken record from my above post, but when the carb/s load up with gas interanlly, it normally a holed float, or a clogged vent. ON a Stromberg, you may also want to check the diaphram to see the conditon of it.

Sounds like you could use a fuel regulator. If you installed an aftermarket electric fuel pump it may be pumping more pressure than you need. You only need 2.5 psi at the carb.

When my mechanical fuel pump failed I replaced it with an electric pump and had a similar problem, too much fuel. I put the regulator on and now it runs great.

I bought a Holley adjustable regulator from my local parts store.

Just a suggestion, take your time when typing your posts and proof read it. I noticed that it is a little hard to follow what you are wanting to get across sometimes. I'm not trying to be mean spirited, just want to help and we must understand what you are trying to say in order to do that.

Can you take the fuel pump off the 79 and use it on the 76.
I agree, it sounds like to much fuel pressure. If that doesn't work or not the full issue try swapping out the ignition components.

Engine swap is not a bad job. I'm on my second engine pull.

Sorry, I'm missing something in your first post. Has the 76 run at all, with either carb on it, or is the problem that you can't get it to run, regardless of the fuel pouring out.

OK< i have tried both fuel pumps and carbs on the 79 parts car and they work,



but on the 76, i tried the original zenith carb and rebuilt it and it didnt work, so i tried the zenith from the 79 which workt GREAT and on the 76 it doesnt, i used the 2.5 psi pump from the 79 on the 76 and still the carb spit fule out in 2 seconds . I HAVE NO CLUE,

NEVER !! ,the 76 ran for 1-3 SECONDS and dies, gets to much fuel or when i turn of fuel pump it runs few seconds on the left overs in ther intake manifold,


COULD it be something to do with the gas tank ?


i might just have to sell both of them in a lot and try to get my money back because thereis nomore to replace, !! and if the everything works on the 79 junk car thenwhy wont it on the 76 !

I have a couple questions TK.

First off, not that it makes much difference, but when you first started posting on the forum you said the car was a '77. Is it actually a '76 or a '77?

Second question is in regards to the fuel pump placement. Is there is an electric installed on the '79 and is it on the frame rail? In earlier pictures it shows your fuel pump on the '76 ('77?) is right up by the carb not on the frame rail by the tank where it should be. If the '79's is on the rail and the other is by the carb it may be jetting fuel into the carb faster than it can handle.

Two suggestions. Try it with the fuel pump at a location closer to the fuel tank or pick up a mechanical fuel pump for like $30. The mechanical pump I just put in my '78 works perfect.

Ugh, dude, I'm sorry. I'd really like to help but it's making me sick trying to watch those videos. WAY too jumpy.

Just on a hunch, what are the odds you've got something wrong with the ignition system on the 76?

No reward. May try this did this on motors before. Do this outside. fire extinsher [spelling] handy. I made a small contailer with small line to carb. Put it above carb. Gravity is enough to run these cars. Plug old fuel line and or remove electrical to pump. If it runs like this problem is in too much fuel pressure. Get a low pressure pump, electrical or pump on block. Me I have a 75 and have a electric pump at the gas tank. Electric pump, they pump better than they pull gas. Don't try a regulator have read here of others trying it and later put in proper pump. Hope this helps. Remember safety is upmost in doing this.

ALSO, if when i took out 1 spark plug, and black smoke was coming out of it when i turned it on ! and it ran for minutes till I turned it off, if theres black smoke coming out of spark plug hole { THE ONE I TOOK OUT} then does that mean the head valves are leaking {CLOSED OR OPEN BLOCKED} ,??would that explain why it wont run with all spark plugs in ? thankyou

if it runs better with only 3 wires connected , you may have them on wrong. firing order messed up

blowing smoke out of an open plug hole doesnt mean anything,it's easier to pump it out that hole than past the exhast valve.

running a motor with one plug out is extremely dangerous. you are pumping a very flammable vapor ,that can be easily detonated by any stray spark.

hook up the plug wires on the bad running motor in the same order as on the good running motor ,firing order 1342

, mywires are correct, is there anything in gas tank or near ot that can brake ?

If there is a problem behind the pump you would not be getting any fuel, but from what you are saying it is the opposite and you are getting too much fuel.

Looking at your picture, I am seeing the ignition wiring going 1,2,4,3 Watching the video you explain you have the wiring as 1243

Correct firing order is 1,3,4,2

You need to get a fuel pressure gauge and check what the pressure is coming out of the pump. You can get an inline gauge fairly cheap, put it as close to the carb as possible, and swap it between the two cars to make sure it is reading the same.

I have a '75 Midget. Should be the same as all the late model cars for the most part. Here is a picture of the distributor and wiring. Also, the stock mechanical fuel pump. You have an aftermarket electric pump.

Sorry missed that video some how. Check the firing order as rest have said. Might to do compression test and or leakdown test. May have one or more cylinders down in compression or like said burnt valve.

I sit corrected, I had forgotten that the MG dizzy runs counter clockwise. My bad.

Yeah I'm thinking ignition too, check firing order is a good idea, but it didn't really sound like that, how about checking the timing.

I think you may have the plug wires not in the correct order .

who got the reward?
