My new MK1

[Dubstein]

Is this buzzing coming from the fusebox? I had this when working on my wiring, getting the headlights to work to a new separate switch (I using a different dash). The headlights are connected to the indicators so there might be a grounding issue or something unplugged, just a shot in the dark. I cant really explain how the wires are set up.. Sorry if it doesn't help but it might

Ill attach my fusebox diagram, but you will probably have the newer model one, which is floating around the internet anyway. Im pretty sure the switch set up is the same anyway.





Im not sure how to go about making this smaller, anyone know how to code a scroll box or spoiler on these forums?

Just a word of warning.

76 and earlier cars used the fuse board / relay plate 'A' version
Later cars used the 'B & C' version. Some of the pin out positions are different.

Easiest way to tell if yours is an 'A' version is that it will have a large square headlamp relay on the left hand end, you will
likely have the metal indicator switch.

proceed with knowledge...

As rocco said Mine is a 76 and doesnt use the b slot.

Mine doesn't use the b slot aswell. I think it was a grounding issue because I recently took the cluster out to check the voltage stabiliser and when I put it back together it works fine

[roccodingo]

By the A , B or C version you need to look at the part number that begins with 171.... the letter at the end is the version.

Had a new 2 inch exhaust made and installed, sounds much better now and now longer rattles

I dont think its running 100% though. Im getting this weird whistling noise when accelerating. Heres 2 videos of the engine running, not sure if you can hear it though.

I was also wondering if anyone know any weber tuners in sydney that can get the carb running perfectly.

Tough exhaust! How much did that set you back?

[gldgti]

Have you changed the fuel supply setup at all?

In your first page, the engine bay pics look like there is no fuel return hooked up. It also looks like you must have an electric fuel pump, as I couldnt see any fuel lines going to a diaphragm pump on the block?

With no return, its very hard for the system to regulate fuel pressure properly. The fuel pump and regulator needs to be able to circulate the fuel and the carbie should be tapping off of this circulating supply. All this means is that the fuel should go from the pump to a tee, with one side going to the carb and the other side going to the return to the tank.

If you get this sorted and check the fuel pressure, it might help it to run right - if the carb is getting too much more or less fuel pressure than about 4psi, it wont work properly.

The exhaust cost just over $400, thats mates rates though.

When i first bought the car it had a electronic fuel pump without the return. It was giving me some issues so i just went back to the mechanical pump at the front of the engine. Ive read some people saying that a return line is not needed with webers when running the mechanical pump.

[abreut]

You definitely do want to return to the tank with the mechanical fuel pump. I used a restrictor in the return line just at the t-piece leading back to the tank. Also one thing you might want to look at is the internal strainer inside the fuel tank. It is probably all gummed up after all the years of sitting and could be causing fuel starvation. You have to pull the back seat out, undo the little manhole cover, take out the fuel level sender and then get a little hook made out of a coat-hanger or something and pull out the strainer. The gauze is very fine so it blocks up easily.
