compression Darmah SD 1981

Post by Willemd »

Hi,
Compression test shows : front cyl 165 psi, rear cyl 163.
Is this a good compression?
Not too much difference between front and rear cylinder?
Anyone?

Thanks
Willemd

2 psi difference is as perfect as anyone could hope for. Get scared when you get reading like 135 and 150 etc...........
