Briggs motor swap / Charging system differences

You might need to find out what engine he has along with the datecode so the correct info from the two APSIs on 21, 28, 31, 330000 series is given if required. Also there is a new torque spec if it is a 21, 28, 31, 330000 series.

hes not grabbing random parts from a junk yard, he would be using the oem charging system that came with the mower, so its an exact perfect matched system

if he wasnt using the oem parts from the original engine i wouldnt be suggesting he use them without checking the specs

Apparently you do not know (or care) there were changes from using an aluminum flywheel key to two different steel keys depending flywheel and crankshaft design on the fore mention series and a new torque spec for tightening the flywheel retainer. IF the OP is working one of the series listed then the associated Briggs APSIs needs to be applied. The engine may already have these applied but it still need to checked to be sure and upgraded if not.

Maybe you one those that just tighten the flywheel retainer with an impact and call it done.
