Most likely .032, but check to be certain...I have a '91 B2200 and am assuming it to be the same.
there is no gapping needed
The correct spark plug gap is 0.052 inch. Try to look for spark plug brands that fit the Mazda M.P.V. engine and already has the factory gap set near to this correct setting.
Gap is 0.031 or 31thousandths. your truck has the 2184 cubic inch engine.
I found the correct gap setting for the 1994 Mazda B4000 to be .054. As found at the auto parts store and Advanced Auto.
0.031 thousandths. or just 31 plain and simple.
Checked my '90 B2200 owner's manual and it sez: Carb: 0.031" (+/- 0.002) Fuel injected: 0.043" (0.004)
The gap setting is .38 to .42
The spark plug gap should be set at 0.032 of a inch with a gap setting tool.This is simple and also suggest using ngk plugs(normal oem replacement) not platinum.Go with these for simple low cost,and ease of install and removal.
.044 is the proper plug gap setting.
