Was tuning up my '72 142E over the weekend (B20 F engine), and got the following readings when conducting a compression test:

Cylinders 1 and 2: 110 lbs.

Cylinders 3 and 4: 120 lbs.

These readings all seem low to me, although I understand that the B20 F had a lower compression head than earlier B20 variants.

Can anyone tell me what the compression ranges should be?

Thanks a lot!
