How did the fault start, was it ok one day and then just appeared, or was I after hard abuse, or engine rebuild,etc.

I think your gonna have to have the head of just to check. Ok it'll cost ya in bits. but u have done the things which I would try. Ok your getting a good compression, but if there is fuel being dumped into the bore and for some reason it is not firing, then the fuel will increase the figures you are given on the compression gauge.

have the followers still ot oil in them if the car hasn't been run for a long time, try squeezing the oil out of them and check if there worn underneath. if there full of oil have pressed so the oil is all out, so they will fil up when u start, if there already full sometimes they have difficulty as stu said if there worn items.
