This has probably already been discussed but anyway...

What sort of compression numbers should I be getting?

I have found out that she is a 1600.

If anyone can help.

Thanks

Richard.

Anything above 100psi is OK if I remember correctly, altho compression testers can give such varying readings from brand to brand that it is more useful to make sure that each cylinder reads the same than the actual pressure.

Cheers.
