I did a compression test on my 1969 Innocenti Mini 850 today after changing the head gasket.
The results were 125 psi at all four cylinders.
I am obviously pleased that they are all the same but I was wondering what the actual psi should be and if mine are on the low side.

It's not really the ultimate number that matters as long as there not very low or very high, it's the variation between cylinders that matters, different gauges will give different values! but if your at 125 across all cylinders your doing just great.................
