Cusser

Compression test never hurts, but as these get more mileage on them the compression can still be like 165 psi in each cylinder and still burn oil from bad oil control rings. But I used my 35 year old American calcualtor and figure you have under 95K miles on it, so you should be good to go. Plus, being in Canada, likely yours is fuel-injected B2200, you lucky dawg !!!
I could drive practically any truck out there and brand new, but I still drive my 1988 B2200 Cab Plus every day. We call them "Cab Plus" here, not extended cab, extra cab, or king cab here, those are other brands' names.
Another great site with good technical data in MazdaTrucking.com - many visit both sites.
