Okay, I have really outdone myself this time.
I pulled out the spark leads from the distributor cap and forgot to mark which lead went where. I realised once I pulled out the last one when it was too late! D'OH
I have been going over the net and through my pics and have only managed to find where one of the leads goes. I am getting slightly confusing info from the net, although everyone is saying the same thing, it conflicts with how my leads were wired up (because of the one lead that i am 100% sure about from my pics).
I tried how they recommended on the net, the order was 1-3-4-2 (1 being the furthest left). As 4 was in the bottom right, i assumed 1 to be at the top left and worked round clockwise as I assume that the engine rotates in that direction too.
I've also bought and put in a new distrubitor cap and rotor arm.
I fired it up and immediately, I could tell that the firing is not right so I switched off the car. I have links below of where i've been reading, and also a helpful diagram on one of the websites which conflicts with what I could see in my pics, but it's still worth showing on here. Could it be the spark leads order or maybe just that the distributor cap and arm are so new, the engine needs to run just a bit?
The car is a 1989 Mk2 Golf 1.3 standard engine manual petrol.
I will also attach a few pics of my engine in case anyone else has better eyesight than me
