Hi-I'll introduce myself later as this is my first post. I have an '86 Ranger, 4 cyl. 2.3L, EFI, 2WD, 5 SP. It has a brand new Jasper rebuilt in it with 200 miles on it. For fun, and future reference, I checked the compression today. It was 190, 190, 182, 193. Should I be at all concerned about the 182 reading? Thanks
