dmartin95 0 Report post Posted September 9, 2010 My Engine is a 16HP Briggs and Stratton, Model# 402707 0145-01 85091312. It's currently sitting on a Simplicity 6216 and was considering doing an engine swap and was wondering if someone could provide the Shaft size on this motor and also the bolt pattern spacing for the engine mount.

BLT 461 Report post Posted September 11, 2010 Tulsa Small Engine has a simple line drawing for mounting purposes and for shaft sizes, I think there was only the 1" Dia X 3" or so long with 1/4" KW. Share this post Link to post Share on other sites
