I'm doing 43-44Mpg now. But i'm not finished yet.
First of all i had to change the breaks. They where like eeeehhhh gone (at least one of the 4 blocks was almost gone). So i saw that one of the two (how do you call that?) scruw holders where stuk (see red circle in the picture). They have to slide so that the break is not making contact whit the break-disc. This is not good for FE and the break is wearing faster than normal.
And i bought some second-hand tools, like a timing light and a vacuum gauge whit numbers. Also some other tools from a garage that's going to stop, so it was very cheap.
