MGB: Breakage

Funniest thing happened to me today on my way to my class at the community college... My throttle broke, and unfortunently, not the throttle-cable component.
The throttle return spring (weber here, mounted 180 from normal, throttle spring runs from arm to inner fender wall) broke off in its hole. Instant 5000rpm of scaring the frigign' cleveland browns right out of my lockerroom. I instantanously reacted, braking, neutrual and ignition off, as visions of exploding engines and clyandars and attached arms flying at my body.

Got back from class, friend drove me to-fro, grabed 2 pairs of needle-nose visegrips and formed me a new hook with the remaining spring and put 'er on to bring me home [10 blocks... ehh]. Not to mention, 1.5" of rain today so far

How should I set this thing up right? JDW you have any pictures of your Weber setup not focused on your plumbing? but of this linkage setup?



recommendations?

Rotate 180 and your there.

You need some sort of spring bracket on the carb or manifold itself. just an L shaped bracket ______l fixed under a carb mount or manifold bolt, (depending on which way the spring must pull), with a little hole to hook the spring in. You need to use a spring with a pretty light pull. The coiled part about 3/8 inch in diameter and about 2" long with maybe about 2" of straight wire on each end to make your hooks or modify the ones already on the spring. With specifications near these you get an easy throttle pedal with good return, plenty of pull area in the spring without stretching it out of shape, and enough wire to put your end hooks where you need them. Make your bracket to fit the space requirements of the spirng. Auto Zone markets Mighty products in red blister packs with "HELP" written across the top and should have several differrent kinds of springs on display. Most other parts stores will have someones display too.

Funny, but I didn't see the picture before. Man that's funkey, turn it around and you can make a sqring bracket out of a straight piece of metal and secure it under a manifold nut. That damn spring is big enough be in a rat trap, I'll bet your throttle pedal pushes about as hard as the clutch. You need a spring with wire about 1/3 the size of what you have.

Your whole setup is different than mine and no pictures of mine will do you any good. Now I see why everybody asks me how I got my throttle cable set up the way it is. It was just part of my kit and I didn't know there was any other way. It looks and works great. Your linkage is OK, but everything else is bass-akwards.

Has that K&N fillter been oiled? They usually look purple after they're oiled, maybe it's just the picture.

I'll check out the Autozone a few miles away, thx John

Blake nailed it. Your carb is mounted backwards. I mount a bracket like John said and use the same spring used on the stock carb. Matter of fact the kits use to come with the bracket to mount to the manifold stud.

My kit came complete with everthing, a really sweet & neat set-up. Even a heated intake when the car heater is turned on, which is the only weather when you need it. Never a minute of trouble with any of it for nine years.

i have no clue what came with my kit :-\ shop installed everything and I got nothing back from my entire old induction system except my hot-air cooler inlet thingy (strange gift eh?)

I mentioned first that she was 180, would it be hard to rotate back to 'normal'? would I need to repalce the manifold-carb gasket if I removed it?


I didn't know it was K&N filter, and thus thats a negative on the oiling

I need to locate another bulkhead style port to put on the filter tray for my evap. system vacuum, that thing is just bad running w/o vacuum I think, if you saw the boogery stuff that forms (and water too) in the hose going from cansister to valve-cover.

PS, should i always hear a nice sucking sound at idle from the oil breather outlet on the weber?

Rotate that carb like it should be, and it will be a lot easier. That big ol spring has bothered me since I first saw it.....I wonder if that shop that installed it had ever seen a properly installed Weber DGV on a B....

BTW, my weber return spring attaches to a little L bracket mounted on the manifold stud. The spring is a stock B return spring used on the SU setup I believe.

If you can't find a K&N service kit locally here is the best source for their producte I have found.



Never wash a K&N filter in gasoline or any kind of petrolium solvent. That will cause it to shrink. One like yours will shrink about 3/8" lengthwise. Follow the cleaning and oiling instructions to the letter and your K&N filter will outlast the car,,,,,,,, and you.

It changed when I posted it. Click on the third blue link about a service kit.

Dammit! You have to click on "Continue/New Search first".

ordered up... you know of Autozone haveing any vent ports that would fit my evap-hose application?

did I do right? 8 bucks at Baxter's for the lot (Bax is closer and i know 3 guys that work there, no discounts, but helpful!)

sure. Red Green would ductape a 5lb weight to the broken spring
I would machine small braket and mount off of carb stud
