Hi, just thought I'd ask some knowledgable mechanics on here...
I have a compression tester which I have used many times sucessfully on various different motorcyles and cars.... It's only a 2 piece tester laser one I think (one fitment for skinny plugs and other for fat ones)
Tried to use it tonight on a Ford KA, but could not get it threaded on....
I assumed spark plug/threads were pretty much all the same, but starting to wonder if there are different size spark plug threads?
Thanks
