B12 engine dilemma

[Glenny86]

Help I am rebuilding a mk2 b12 engine and seem to have two of these pins with spring's I no 1 of them if for the neutral switch but I don't know where the other 1 go's .

Its the neutral switch plunger, there should be  only one

looks like you have a spare

[Slabby11]

If your switch has 4 wires one of those pins will be the normal gear position wiper the other is for earth to ensure the cdi gets a good signal.

Im sure the the 4 wire ones ive got only have one pin????

 

this is the same as the K4 mark 2 ive got, ive also got a K6 engine as well ill have a look tomorrow..

So the K6 engine ive got in bits has the central pin as well as the outer pin, the spare engine I have that turns out was from a 2002??? has just the outer pin like the mark 1's?????

No - those don't have the spring location peg, and are a lot shorter.
