I'm pretty sure mine is actually 32cc and the A/V doner saw was really 38cc - however they are both early saws, and I recall seeing somewhere that replacement parts were only available in 38cc.  So maybe they figured out what Poulan did that it wasn't cost effective to make several displacements so close. 

The oil pump is under the flywheel, but I did not take it apart as mine worked fine.  The pump is driven by a worm gear concentric with the crank, but the gear spins freely on the crank - there is a coil spring between the flywheel and the worm which drives it but acts like a clutch.
