What should the compression on a B21ft be? 200

Hello,

130 psi is fine. I would not be at all concerned with the 5 psi difference between cylinders. This is definitely within tolerance. I measured my B21FT several years ago, and I believe that mine was around 130 to 145 (my car has been very well maintained, also). Anyway, yours sounds just fine.
