Jesse Rieber 28 #1 Posted May 3, 2020 I have a D 160 wheelhorse with an Onan B43M engine. Some nice person on Red Square made available an original FOS manual for Onan engines. The title states it covers 16, 18, 20 and 24 Hp engines. The B43M is a 16 HP engine. However, as I get into the manual I notice specs for the B43E, B43G engines (16 and 18 hp respectively) but nothing for the B43M. Are the B34M and B43E (both are 16 hp) essentially the same engine with the same specs and procedures to repair? Jesse A. Rieber Share this post Link to post Share on other sites
